Use of laser in cataract and Lasik surgeries

In cataract, the clouded lens is removed by surgery and it replaced intraocular lens, which is an artificial lens.  The removal of clouded lens is done through either of the two surgeries. These surgeries are known as small incision surgery and standard extracapsular extraction. In the first surgery, the surgeon uses small incision to pass the sound wave to break up the clouded lens into smaller parts. These parts are then sucked out of the eye.

In the extraction method, the front portion of the lens is opened up to remove the lens in one piece. The one of the common problem, faced by the patient is the clouding of lens capsule after five year of cataract surgery. This clouding is not considered a serious issue and a laser is used to treat this clouding.


For patients with Cataract Surgery in Delhi cataract in both eyes, the operation is performed only in one eye and then after a gap, the second surgery is performed. The surgery is never done simultaneously on both eyes. For patients, who have both glaucoma and cataract, the surgery is done for both issues at the same time. Cataract surgery can be done without hospitalization. The time taken by the surgery is less than one hour.

Lasik surgeries are used on patients to treat cases of shortsightedness, long sightedness and astigmatism. The surgery is done to reshape the cornea so that light is focused on the retina for clearer vision. The surgery is pain free and can be performed in 15 minutes. The results can come within 24 hours. The use of laser comes in all Lasik surgeries. The laser is used to treat the underlying area of the cornea and to reshape the areas for clearer vision. The flap is cut by the small knife. Then this flap is just kept side to treat the underlying area. After treated the underlying areas, the flap is put back in the place to cover the area from where cornea tissue was removed.

In Lasik laser surgery, Lasik laser in Delhi the laser is used to cut the flap of the cornea. The use of laser for cutting cornea flap is gives exact shape of the flap .The Lasik surgery is considered one of the most successful surgeries with rate of success touching above 96 %. The clarity in vision comes immediately after the surgery and it involves no stitches and bandages.  After Lasik, the patient may feel no need for contact lens and glasses. After cataract, the reading glasses may be needed by the patient according to age conditions.

Basic of cataract surgery and use of Lasik laser

Cataract surgery is done to remove the cloudy lens of the eye. The need for this surgery may come after 50 years of age or due to injury to the physical or chemical injury to the eye. The surgery involves removal of the cloudy lens and placement of manmade lens in its place. This manmade lens is called intraocular lens. The lens is permanent and need no maintenance.

In cataract surgery, the high ultrasound device that breaks the cloudy lens into smaller pieces and these pieces are removed from the eye by suction. The small cut is made at the side of the eye for the suction of smaller cloudy lens parts. After the removal of all smaller parts of the cloudy lens, the manmade lens is places behind the iris and pupil, exactly at the place, the position of cloudy lens. After inserting the lens, the cut is closed; the stitching may or may not be required. Then the protective shield is put on the eye during the initial days of the recovery. The actual surgery takes Cataract Surgery in Delhi place in less than half an hour. The patient has to follow the instruction and recommendation given by the surgeon for proper recovery.  Surgeon may also advice patient against taking certain exercises and activity during recovery period.

Lasik Laser in Delhi

Use of Lasik laser surgery –

The use of laser in the cataract surgery has been approved by the United States in many hospitals in the country. This laser is the same laser that is used to create flap in to treat the area under cornea for curing short sightedness, high sightedness and astigmatism.   The laser in Lasik surgery is used to cut the cornea flap and then reshape the area under the cornea by keeping flap aside. The lasers are used in non –laser surgeries also. But in Lasik laser surgery, laser is also used to cut the cornea flap. In cataract surgery, the laser fragments the cloudy lens into smaller parts for removal. With the use of laser in the cataract surgery the need to make cut for removing smaller cloudy lens is not required.  The cost of laser cataract surgery may be high for some patients and only some hospital are equipped with the facilities to provide laser surgery in cataract. The studies have confirmed that Lasik laser in Delhi laser use   improves the accuracy in cataract surgery and recovery chances also improve tremendously with the use of laser.

Process Involved In The Cataract Surgery

Cataract surgery is performed to inserted man made lens in the place of cloudy lens .This man made lens is called intraocular lens. The eye lens can become cloudy due to natural process of aging or any injury to the eye. Before the cataract surgery, the surgeon examines the eye health, general health of the patient and then discusses the complication which may or may not arise during or after surgery.

The actual surgery is given on the outpatient bases and patient can go home during same day. The duration of the surgery is very brief. Just before the start of the surgery, local anesthesia is given. Some drops may also be given to numb the eyes.  The surgery is done with a method called phacoemulsification. In this method, a small cut is made at the side of the cornea. A device sending ultrasound vibrations is put inside the eye to break the cloudy lens into smaller pieces. These smaller pieces are the vacuum out through that cut at the cornea side. The laser may also be used to make the cut. This use of laser is done with hope to improve the recovery from surgery.

Lasik Laser in Delhi

The lens which is placed is plastic, silicon or acrylic lens. This lens is placed at the exact place, where the cloudy lens was. The intraocular lens is permanent and does not require any change. The after the surgery, the patient is shifted from operation room to other room.  General anesthesia is rarely used in during cataract surgery. Some patients are conscious during surgery with some sedatives. The cataract surgery is Cataract Surgery in Delhi not done on both eyes simultaneously. The difference of few weeks is kept between two operations.

Lasik surgery is done to treat vision cases of myopia, long sightedness and astigmatism.  The use of laser is done to reshape the area under cornea after keeping aside the flap in the cornea. Lasik surgery involves totally use of laser to cut the flap and treat the area under the cornea for curing vision problem. A cool ultraviolet beam of light is used to remove tissues from the cornea and improve the vision .The only difference between Lasik and non Lasik surgeries is that in latter, the laser is used only to reshape the cornea area. The flap is cut manually by a small knife.  The use of Lasik surgery Lasik laser in Delhi improves the accuracy of cornea flap and chances of recovery are fast and permanent.

Cataract surgery and its effects

Cloudy the eye lens is known as cataract. Usually it is due to aging process but injury to eye can also cause cataract. The patient should immediately consult the eye surgeon because any delay may lead to permanent blindness. Cataract surgery involves removing the cloudy lens and replacing it with man mad new lens. Some cataracts do not grow into serious problems, and stay without causing any vision problem. But other grows into serious issue and blurs the normal vision.  When a cataract progress, the entire lens of the eye becomes white and cloudy, this stage is called ripe or mature stage .it causes serious vision problems. As a rule, the cataract should be treated before is goes beyond surgery stage.


Cataract surgery –

Cataract surgeries are done by a technique called phacoemulfication.  In this surgery, the cut is made to harder part of the lens is liquefied and then vacuum out , The cut is made at the side of the cornea. The surgeon uses local anesthesia, before the start of the surgery. The device is inserted into the eye to   send ultrasound into the eye. This ultrasound breaks  the clouded lens into smaller pieces. The smaller breakaway pieces are then vacuum out through the cut from the side of the eye. After the surgery, the man made lens called intraocular lens are put in the eye.

This intraocular Cataract Surgery in Delhi NCR lens can be plastic, silicon or acrylic and has optical power that is chosen by the surgeon to give normal vision to the patient.  This lens needs no special care and is permanent. The duration of the surgery is not more than an hour and is done on outpatient basis. The patient can go home on the same day. But the patient has to follow certain guidelines for several days after the surgery.  The surgery is not given to both the eyes at the same time. Generally one eye is treated and the results are analyses before start of surgery for other eye. There has to be some time gap between two surgeries.

After surgery –

 Surgery is very safe and successful in more than 98 % of cases. Some patients in rare cases may develop some complications, which are transient in nature. Surgeon can recommend some over the counter drugs to cure mild irritation in the eyes. The wear of dark eye glasses is recommended to protect eye from lights.  The patient is also prohibited from strenuous exercises or swimming for few a weeks. .During surgery, the outer lining wall of the cataract, is left in the eye to hold the replacement plant. In some cases, the clouding of this lining may occur after some times. Then a laser Lasik Laser in New Delhi called YAG laser is used to give back normal vision by opening a small hole. This procedure does not involve any pain and it’s effortlessly done by the expert surgeon. The replace lens is not removed.

Types of Cataract Surgical Procedure and Benefits of the Lasik Laser Surgical Procedures

If left untreated, the cataract can cause permanent loss of vision of the individuals. For the ensuring perfect vision, the natural len of the cataract patients are removed surgically and it is replaced with an intraocular lens for the purpose of restoring the lens’ transparency.

The procedures of removal of the natural lens of the eye are called cataract surgery. Different types of surgical procedures used for the purpose of treatment of the cataract are discussed in this blog.  The second part of the blog discusses that the benefits associated with the lasik laser surgical procedures.

Different Types of Popular Surgical Procedures of the Treatment of Cataract

Broadly speaking, there are only two types of surgical procedures that are used for the purpose of treatment of cataract by removal of the natural lens of the eye. First surgical procedures are known for Phacoemulsification or commonly known as Phaco. Other surgical procedures consist of two different types of extracapsular cataract extraction (ECCE). For the purpose of maintaining the Len’s transparency after the removal of the natural len, most of the cataract surgical procedures inserts intraocular lens.

Cataract Surgery in Delhi

Two types of intraocular lens are commonly inserted for attaining the lens’ transparency.  Common types of intraocular lens inserted in cataract surgery are foldable lens of 2-3 mm Phaco incision and non foldable lenses.  For the insertion of the foldable lens, an ophthalmologist or eye surgeon have to make small incision where for insertion of unfold able intraocular lens, an ophthalmologist have to make a large incision of 10-12 mm.

About 90% of the Cataract Surgery in Delhi is successful in restoring the useful vision of the individual. Quick post-operation recovery, minimally invasive and small incision, make the cataract surgery highly demanded for restoring the normal vision of individual suffering from the cataract.

Different Types of Cataract Surgical Procedures and Benefits of Lasik Laser Surgical Procedures

Surgical removal of natural lens for the purpose of treatment of cataract is known as cataract surgery. Different types of surgical procedures for the treatment of cataract are discussed in the first part of this blog.

Different Cataract Surgical Procedures Used For the Treatment of Cataract

One of the most common types of surgical procedures common for the treatment of cataract in many developed countries is Phacoemulsification. The procedures of Phacoemulsification involve the use of sophisticated machinery with an ultrasonic handpiece. The hand piece of the machinery is equipped with steel tip or titanium. For the purpose of emulsification of natural lens of eye, the tip vibrates at ultrasonic frequency of 40000 Hz.


Other procedure that is used for treatment of cataract is Manual small incision cataract surgery or popularly known as MSICS. The manual small incision surgery is evolution of ECCE. In these surgical procedures, the len is expressed out of the eye through a self sealing scleral tunnel wound.

Removal of almost the entire natural len through surgical procedures where elastic lens capsule is left intact is known as ECCE. The left elastic len allows implantation of intraocular lens once the surgical removal of natural len has carried out.

Surgical procedures, in which the removal of lens and surrounding lens capsules in one piece, are known as Intracapsular cataract extraction.  Femtosecond laser and Cryoextraction are other surgical procedures that are used for removal of natural len of eye for treatment of cataract in the most efficient manner.

After the successful removal of the natural len of the eye, through different Cataract Surgery in Delhi mentioned in the above paragraphs, procedures of intraocular lens implantation are carried out.

In the intraocular lens implantation, an intraocular len is implanted through small incision using foldable IOL. The implantation of the intraocular len through enlarged incision makes use of PMMA lens.

Some of the Benefits of Lasik Laser Surgical Procedures

In the second part of this blog, the benefits of the lasik laser are discussed. Lasik laser is associated with several advantages as compared to other vision correction procedures. It is considered to one of the most successful vision correction procedures with more than 92 to 98% success rate.

Keratoconus and Cataract: Symptoms and Treatment

A degenerative disorder of the eye, which is very common in India, is keratoconus that causes structural changes within the cornea. Clouding of the lens in the eye is known as cataract and can be treated by removal of natural lens through surgical procedures.

Symptoms, diagnosis and treatment of keratoconus and treatment of cataract are discussed in this blog.

Symptoms Associated with Keratoconus 

Lasik Laser in Delhi

Blurred vision that cannot be corrected with corrective glasses is one of the earliest signs of keratoconus. As per the recent studies conducted, it was reported that the symptoms appeared at early teen age years of the patients such as increased light sensitivity. Furthermore, other symptoms associated with keratoconus are difficulty in vision at night while driving.

Especially at night, the patients suffering from the keratoconus can experience a halo around lights and ghosting. Eye strain is also associated with the patients suffering from keratoconus. Furthermore, headache and general eye pain are also associated with patients suffering from keratoconus. Excessive eye rubbing and eye irritation are also associated with the patients suffering from keratoconus.

Diagnosis and Treatment of Keratoconus

One of the popular methods of diagnosis of Keratoconus is slit-lamp examination. Corneal thinning and Fleischer’ ring, are things for that the doctors looks during their slit lamp examinations. Stress lines caused by corneal thinning are important role in diagnosis of keratoconus. Scarring at the apex of the cone plays important role in diagnosis of keratoconus.

Treatment of keratoconus can be done through lenses and surgical procedures. Corrective glasses or soft contact lenses can be used for treatment of keratoconus in its early stages.  Hybrid lenses and scleral lenses are used for treatment of keratoconus for advanced or very irregular keratoconus.

Keratoconus Treatment in Delhi can be done through surgical procedures such as corneal transplant. In accord to recent study conducted, it was reported that about 11% to 27% keratoconus was treated through corneal transplant, as the vision correction is no longer possible.

Other surgical procedures used for treatment of keratoconus are Epikeratophakia. As per the study conducted, it was reported that the keratoconus can be treated through corneal ring implants. Cross linking and radial keratotomy are used for treatment of keratoconus through surgical procedures.

Cataract Treatment

Cataract can be treated through different surgical procedures, which are used for removal of len. Phacoemulsification (Phaco) is one of the most popular surgical procedures used for treatment of cataract in Delhi. Cataract Surgery in Delhi such as Manual small incision cataract surgery can be used for effective treatment of cataract in Delhi.

Other cataract surgery used in treatment of cataract is Extracapsular cataract extraction (ECCE). Furthermore, doctors or cataract surgical procedures used for treatment of cataract is Intracapsular cataract extraction (ICCE). In different surgical procedures, the doctor makes use of Cryoextraction, for treatment of the cataract in the most efficient manner. After the removal of the natural len of the patients, the use of intraocular lens is used for restoring vision of the patients suffering from cataract.

Symptoms of cataract and cataract removal surgery

Cataract is the clouding of the eye lens, which prevents the passage of light and blocks the vision. Though, cataract is related to old age, it can also happen due to injury, disease or inflammation of the eye.  Cataract can lead to blindness that is why the surgery must be done to prevent the further deterioration in the lens of the eye. Surgery is the only mean to treat cataract. The common symptoms of the cataract are:  cloudy vision, interference with daily activities like reading or watching TV, sensitive to light, especially to headlight, sunlight, halo or haze around lights. The increase in cataract condition can also decrease the ability to distinguish between colors. The double or multiple visions also starts in the initial stages of the cataract. This problem comes to an end with the growth of cataract. The patient suffering from cataract also may change frequently, the number of spectacles or eye glasses. Some persons with cataract also may get improved near vision with onset of cataract but this is temporarily and vision gets worse with growth in cataract.

Cataract surgery is done to remove the cloudy lens and put clear artificial lens in its place. The advanced cataract surgery is called phacoemulsification, or phaco. In this surgery, the cloudy lens is disintegrated into small pieces with the help of an ultrasonic probe. After gently washing out the debris, the new artificial lens is put in its place.  The incision of only 2.6millimeter is required in this surgery. This incision is self healing. The stitches are not required in this surgery.

Before the surgery, the local anesthesia is given. This reduces the sensation of pain and also prevents Cataract surgery in Delhi the movements of the eye during surgery. Eye drops as anesthesia are placed on the eye. This prevents the pain sensation but does not prevent the movements of the eye. But under both anesthesia, the person is awake and in full awareness during operation.

The artificial lens, which are inserted into the place of cataract lens are of two types. The folded lens and non- folded lens .The non folded one are made with hard plastic and large incision has to be made to insert them. Folded one are made from soft acrylic plastic. The incision for inserting them into eye has to be very small. They do not require any stitches and healing time with them is only 4-5 days. The chance of any infection is also to zero.

Again the folded lens can be monofocal or multifocal. The monofocal lenses give enhanced vision but for near vision the patient has to wear glasses. This monofocal provides improved vision only for one distance. It cannot change like the original lens. Only the use of multifocal gives Lasik laser in Delhi independence from glasses.  The multifocal lens has improved vision for at both distance and near points.  More than 80 % patients will never need any glasses for any activity. The remaining 20 % also prefer multifocal for both near and distance visions.

Types of Surgeries Performed to Remove Cataract

Cataract is the cloudiness of the lens of the eye. This is due to aging process or due to some physical injury to the eye.  During the cataract surgery, the cloudy lens is removed and is replaced by clear lens, which is a manmade lens.

There are three types of surgerical techniques, by which the cataract is removed. In the extracapsular type, which is also most common technique used in the treatment, the surgeon makes a slit at the side of the cornea and removes the cloudy section of the eye lens.   The rest of the lens is vacuumed. This type of procedure is used in case of advanced cataract.

In Phacoemulsification ,small incision is made in the side of the cornea and then an ultraviolent vibration are send to the eye to break the cloudy lens into small parts. Then these small parts are sucked out by making a small incision in the eye. In the older type of cataract surgery, the lens is taken out in one piece. Though, this surgery is rarely used today, but may be required in cases of trauma or dislocation of lens.

The lens which is put in the place of old cloudy lens is called intraocular lens. This lens comes with an optical power selected by the surgeon to give normal vision. This lens does not require any special care. The function of this lens is to focus light onto the retina and improve the vision. Cataract surgery does not require a patient to stay in the hospital and can be done in one hour.  Patient is under some kind of sedative and numb drops are given to the eyes before the start of the surgery. If both eye need cataract surgery, the only one eye is treat at the time and next eye is treated after 4 – 8 weeks. The result of one eye will determine the next surgery in other eye.

The use of laser is bit expenses Cataract surgery in Delhi compare to other methods of the cataract surgery. The laser use improves accuracy but has no major impact on the result of the cataract surgery. It also does not reduce the recovery time.

Cataract its Causes and Cataract Surgeries


Cataract Surgery in Delhi

Cataract is clouding of the lens of the eye due to protein build up.

The exposure to certain drugs such as corticosteroids or diuretics, ultraviolent rays of sun, radiation or advance stage of diabetes can also cause cataract. Injury to eye, consumption of alcohol, heavy smoking, long term use of steroids, air pollution can also lead to cataract .Any disease in the eye such as glaucoma, retinitis, retinal detachment, pigmentosa or long term uveitis can also progress to cataract. The potential risk to cataract is there for a person with family history of cataract.

Surgery is the only way to get rid of the cataract .There is two kinds of surgeries and use of any surgery will depend on the kind of cataract one has. Though many people can work well with contact lens and glasses. But in serious cases, when the vision is deteriorating and vision loss is possible for ever, then surgery is suggested. In adults, the degree of vision affected by the cataract determines the surgery need and in children the surgery need depends on the degree of interference with normal vision development.

In small incision surgery, sound waves are used to break up the lens into smaller pieces .Laser is also used to break the lens .This is the most common way of removing cataract . In the second called extracapsular cataract extraction surgery, the lens and its front portion, is opened and then removed in one piece. Second surgery is given to person who have cataract in both eyes. The surgery is not done on both eyes. Cataract surgery in Delhi. The first eye is given time to heal and then depending on the improvement in one eye; the surgery on another eye is performed. Anyone with glaucoma and cataract diseases, the surgery can be given at the same time for both the conditions.

Lasik laser in Delhi

After the surgery, the clouding of posterior lens capsule may occur within 5 years. But it is not considered as a serious problem and it treated with a laser surgery. Since the possibility of vision loss is always present with the cataract, the services of an eye specialist should be taken without loss of time. For people with other eye conditions such as farsighted, nearsighted or astigmatism, LASIK surgery is given to correct the vision. Lasik laser in Delhi. The main function of the LASIK surgery is to reshape the cornea, so that the light is properly focused on the retina. The need for contact and glasses also comes down after LASIK.
