Cataracts are perhaps the most common forms of blindness in the world. Most people do not reach the doctor to correct it. But, conversely, the problem can be fixed with a simple surgery that can revive vision immediately. It is generally a normal process of aging, but some cataracts can develop due to early-onset diabetes or other health complications. Cataract surgery in Delhi is perhaps the safest procedure that you can have.
What is Cataract Surgery?
The clouding of the lens in the eye is called a cataract. The surgery involves removing the clouded lens and replaced with an artificial lens. The Intraocular lens that is inserted in the eye restores vision dramatically.
The cataract surgery in Delhi is generally done on an outpatient basis, or some patients with any previous complications may have to stay overnight. The procedure involves high-frequency ultrasound devices that break the cloudy lens up, and these are then removed from the eye with suction. The Phacoemulsification process, as this is called, reduces risks from complications. The incision is minimal and helps heal the eye faster. You may need a protective patch for a day. After this, you can resume normal activities, and keep putting the prescribed eye drops to promote healing.
The most recent form of cataract surgery is with the LASIK laser. These lasers have got the approval from the FDA and can be used to perform cataract surgery by creating corneal incisions to allow access to the damaged lens. Phaco is again the instrument of choice, although the energy used is very little. Laser-assisted cataract surgery is not cheap, but the accuracy of the laser is unparalleled.
Preparing for a Cataract Surgery
The doctor will perform a series of tests to check your overall health and ascertain whether any issues may impede healing or damage to the vision at a later date. She will conduct an eye refraction test to determine the farsightedness, nearsightedness, or astigmatism that you might be suffering from. The curvature of your eye is also measured along with the length of the eye. These are needed to choose the IOL that you will need. You can get IOL’s that correct all vision problems, including presbyopia. You will be required to report to the clinic a few hours before the surgery.
Cataract Surgery Recovery
The surgery typically takes about fifteen minutes. The eye dilation takes longer and so you will need to be at the clinic earlier than the operation time scheduled. You may need to stay for a couple of hours to get the post-operative evaluation done. It is generally advised that you have someone with you during the surgery to help you get home, especially if you need anesthesia.
The standard procedure is to prescribe a couple of different eye drops that need to be administered several times during the day for about a month. The drops are slowly tapered off. You might need to wear a protective shield for a few days. The eyes need to be shielded from bright sunlight with unique post-operative sunglasses. The eyes heal within a week, and a little redness and soreness are normal.
You will be asked not to shower with your eyes open as water may cause infections. No hot tubs or swimming is allowed for two to three weeks. You will probably be advised not to do any strenuous activity for the period. The important thing is to protect your eye from dust and grime or pollutants.
