Types of cataract surgeries and benefits of lasik laser in delhi


The main purpose of cataract surgery is to remove the cloudy lens and  put man made lens in its place . This man made lens is known as intraocular lens. The surgery is done when vision deterioration has led to the conditions where the patient cannot function properly in the day. The aim of the surgery is to help person to get the vision and return to normal working  life.

Persons who have cataract in both the eyes can get surgery only in one eye and second surgery can only be performed after gaps of few weeks   . The surgeon can select one of the two main surgeries for the patient . The selection of  surgery depends on the condition of the cataract  and general health of the patient .

In small incision surgery ,an incision is made at the side of the eye to pass the sound waves to  break the cloudy glass into smaller pieces . The broken smaller parts are then sucked out of the eye .

In extra capsular extraction method   the lens is removed in one piece and manmade lens  is inserted. In this surgery , the lens and front portion of the lens capsule wrapping around the lens is opened  to remove lens .


After the surgery, Cataract Surgery in Delhi the patient has to stick to the medications prescribed by the surgeon. The patient is prohibited from certain activities and exercises.  Persons even after surgery  may need reading glasses due to age factor. After cataract surgery , the lens may get cloudy after five years . But this is a normal problem and gets treated with laser surgery without any complication



Lasik surgery is done to cure the short sightedness, long sightedness  and astigmatism. The use of laser is involved in all surgeries to reshape the cornea . But in Lasik surgery , the laser cuts the flap of the cornea and also treats the area below the cornea after keeping flap aside . The manual blade is not used to cut the flap of cornea.  The use of Lasik laser in Delhi laser improves accuracy and also the rate of success involving Lasik is above 90 %.. The need for stitches is totally eliminated and recovery time also comes down . It is also reported that after the use of Lasik, the need for glass and contact lens comes down drastically and some patients may not need them at all . The use of Lasik depends on the facilities available in the hospital and experience of the surgeons .

Cataract Surgical procedures and Limitations of Lasik Laser

Impairment or loss of vision can be caused due to metabolic changes of the crystalline len fibers over time lead for the purpose of development of the cataract. Treatment of cataract through cataract surgical procedures is discussed in the first part this blog and limitation of the lasik laser surgical procedures are discussed in second part of this blog.

Cataract Surgical Procedures

Day care and high volume coupled with minimally invasive make the cataract surgical procedures highly effective in restoring vision of patients suffering from impairment of vision due to cataract.
Furthermore, small incision with quick post-op recovery makes the Phacoemulsification as one of the successful cataract surgical procedures for restoration of vision by removal of natural len.

For restoration of the vision, ophthalmologist or eye surgeon make use of two types of cataract surgical procedures. Phacoemulsification (phaco) and extracapsular cataract extraction are different types of surgical procedures for restoration of vision.
As per recent survey, it was reported that the more 90% cataract surgical procedures are successful in restoration of patients, with extremely low complication rate. Strong glare from lights is one of major symptoms of the cataract. Reduced acuity at low light levels is another symptom of symptom.

Cloudy natural cataract lens can be removed through the cataract surgery procedures and are replaced with intraocular lens for the restoration the lens’ transparency. Natural len of the individual suffering from cataract is removed through surgical procedures, for effective restoration of the vision that was hampered due to opacification.  

The implantation of the intraocular lens can be carried by eye surgeons, for restoration of vision. Foldable lenses of 2-3 mm phaco incision are generally implanted or inserted after the Cataract Surgery in Delhi, for restoring the transparency of the len.  Larger extracapsular incision is required for insertion of the non foldable intraocular len after the cataract surgical procedures.  The size of the non foldable lens is about 10-12 mm and often requires stitching for the purpose for ensuring accurate implantation.


Limitation of the Lasik Laser Surgical Procedures

Although lasik laser is associated with high success rate of 92-98% but if carried out by unqualified eye surgeons, the lasik laser surgical procedures are associated with certain limitations. Changes made to the cornea at the lasik laser surgical procedures cannot be reversed. Other limitation of lasik laser surgical procedures is that additional lasik laser surgical procedures can only be performed for further correction of vision. Lasik Laser in Delhi is very technical complex and doctors cut the flap that can affect permanently affects vision.

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.

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.

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.


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.

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.
