We perform phacoemulsification, which is the most advanced technique for cataract removal worldwide. The surgery is performed through a tiny incision, less than 2.2mm. Unlike in the past, when cataract surgery used to require injection(s) around the eyeball, we use only topical (eye drop) anaesthesia (see below). The latest foldable IOLs are used for clear unaided vision.
Topical (eye drop) anesthesia
What is it?
It is an injection-free procedure where only eye drops are used to anaesthetize the eye.
Why is it better?
- No risk of eyeball perforation, as with needle anesthesia
- No risk of bleeding
- Instant recovery
- No need to stop anti-coagulants
- No need for patching
Why Newer IOLs (Intraocular lenses)
Aspheric single-piece foldable IOLs – Better stability and centration of IOL, small incision and improved clarity
Multifocal IOLs – Spectacle-free vision for all ranges
Toric IOLs – Can correct astigmatism for better unaided vision
Common Myths (misconceptions)
Cataract should be operated only when it becomes “mature” (total)
This concept originated with old format of cataract surgery called ICCE, where the cataractous lens was pulled out of the eye with a forceps or a cryo machine. If attempted on immature cataract, it would lead to lens rupture and complications. Current procedure, phacoemulsification, emulsifies the lens and hence is best performed at a stage when the cataract is not advanced, but progressed enough to decrease vision. Waiting for a cataract to mature can lead to several complications and is no longer recommended.
Cannot take a bath or cook for a month after surgery
Again these relate to the “old” technology. With modern cataract surgery, the patient is allowed to take a shower within 24 hours. Most patients can have a head bath within a week. Cooking responsibilities can be resumed within 48-72 hours following surgery, while wearing protective goggles.
Minimal interval between two eyes should be six months
New technology allows performing second eye surgery within a week after the first eye procedure. If there is significant cataract in the second eye, there is no medical reason to wait. Early surgery in the second eye brings balance to both eyes and allows prescription of spectacles for both eyes at the same time.
Eye donation cannot be pledged after cataract surgery
As a matter of fact, many eyes currently used for “eye transplantation” are obtained from donors who had cataract surgery in their eyes. Modern surgical techniques adequately protect the tissues essential for transplantation.
Diabetics have a poor outcome
A large majority of the patients undergoing cataract surgery have diabetes. Adequately controlled diabetes allows safe surgery and the result is no different from that in non-diabetics. Good control of diabetes and regular evaluations for diabetic retinopathy, however, are essential to preserve the good outcome.
IOL is unsafe
Most complications that result from cataract surgery are blamed on IOL. This is not true. The IOL is a bio-inert material and does not harm the eye, unless placed or positioned incorrectly. Mishandling of IOL causes complications.
Did you know?
Cataract can occur even in children. Either they are born with cataract (congenital) or develop after few years (developmental). Pediatric cataracts require meticulous evaluation, special surgical skills and postoperative strategies for a successful outcome.
