Best Cataract Surgery

A cataract is the clouding of the natural lens of the eye. It is the most common cause of vision loss in people of age 40 and is even the leading cause of blindness in the world.

Cataract surgery is performed by an ophthalmologist, an eye doctor. Your ophthalmologist will examine your eye condition and if needed will perform the surgery.

A cloudy lens blocks light from concentrating properly on the back of the eye which points to a range of vision difficulties. These may include:

• Blurred Vision
• Sensitivity to Light or Glare
• Poor Night Vision
• Difficulty driving or using a computer
• Double Vision
• Colours appear faded or dim

There are various types of cataracts, some of them are:

• Subcapsular Cataract – Cataracts occurring at the back of the eye lens.
• Nuclear Cataract – This occurs in the central zone of the eye’s lens. 
• Cortical Cataract – White Wedge-like opacity that starts at the edge of the eye lens but slowly works its way to the centre (Nucleus).
• Growing Ages – Nearly half the population by the age of 60 develops cataracts and about 80% of people get a cataract in at least one eye by the age of 70 years.
• Traumatic Cataract – A direct injury or trauma can cause damage to the eye leading to cataracts. It can be progressive or instantly after a trauma.
• Metabolic Cataract – Various disorders in body metabolism including autoimmune diseases like diabetes and galactosemia can cause cataracts over time.
• Secondary Cataract – In several cases, cataract develops as a result of some other primary ocular disease such as chronic eye inflammation or glaucoma.

Steroid-induced Cataract – Excess intake of oral steroids or inserting steroid drops in the eye can create cataracts. It is always recommended to ask a doctor before using one.

Cataracts normally affect patients over age 55, but anyone can catch this problem. They occur due to the normal ageing process. Other reasons can be:

• Poor lifestyle habits such as prolonged use of steroids, smoking or alcohol intake.
  
• Environmental factors such as over-exposure to harmful UV rays of the sun.
• Auto-immune diseases like Diabetes, Obesity & Hypertension
• Eye injuries or a history of eye diseases in the family.

In general, there is currently no way to stop age-related cataracts.
Though, people with diabetes may reduce their risk of developing cataracts by fully controlling their blood sugar levels.
To help stop infection-related congenital cataracts, women must get checked with their doctors about their demand for rubella immunization before becoming pregnant.

Nothing, as such you have to take care of a few things like inserting the eye drops suggested by your eye doctor several. We ask that you begin eye drops 4 days before eye surgery. These drops will not harm your vision. They are used to prevent and control inflammation, infection and pain. You will maintain these drops for 2 weeks after surgery. You will also be provided with a detailed pre and post-operative instruction sheet before surgery with exact directions on how to take your eye drops.

The cataract procedure itself only takes 10‐20 minutes. However, aftercare requires a certain period of time.

Most normal activities can be continued within a day of surgery. In common, you should begin a normal life but avoid very difficult tasks like sports. Do not rub your eye and avoid swimming for 1 week after your surgery. Your ability to drive will depend on how fast your vision restores and the contrast among your eyes after the surgery.

This will depend on the kind of intraocular lenses (IOLs) used for you. The high-level intraocular lenses such as multifocal or accommodating IOLs exceedingly decrease dependency on glasses. In most cases even reading glasses can be avoided.

During cataract surgery, your surgeon will give you local anaesthetic numbing eye drops to prevent you from experiencing pain throughout your procedure. You will also be provided with a mild sedative to assist you to relax. Depending on the patient and the kind of procedure, extra medication may be used.

As the medications wear off, you may feel a scratchy sensation or slight soreness in your eye the first day. Over-the-counter pain relievers can be done to ease discomfort. If important, your doctor will guide stronger pain medication.

With any surgery, you will experience pain, infection, swelling, and bleeding. Cataract is one of the safest surgeries. But very few people undergo serious cataract surgery complications. In a few cases, side effects from the procedure can be managed with medication.

To decrease your risk after cataract surgery, be positive in following the directions of your surgeon, and describe any unusual symptoms directly.

No, a cataract can’t develop up again as the IOL implantation never requires maintenance and replacement. It is very rare in few patients that a cloudy film is formed behind the implant on the lens capsule membrane, normally a few months later after the surgery. This condition is named a secondary cataract.

In 20-30% of cases months later after the surgery, the posterior part of the lens capsule that is left inside the eye while surgery for security reasons becomes cloudy, causing vision to again become blurred. This is a secondary cataract. That is also called posterior capsular opacification which normally can be simply treated with a less invasive follow-up procedure called a YAG laser capsulotomy.

No, usually in cataract surgery one eye surgery is performed at once. The doctor cannot operate both eyes together. This enables the surgeon to judge the outcome of the first procedure before operating on the other eye. This evaluation may affect the decisions made for the second surgery, particularly in cases using an accommodative or multifocal lens

The procedure of Extracapsular cataract surgery is usually applied to the person suffering from the most advanced cataract and the lens is very thick to dissolve into fragments or when phacoemulsification is impossible. Extracapsular cataract extraction normally needs an injection of numbing medication around the eye and an eye patch after the operation.

The Intracapsular cataract surgery technique needs an even more open wound than extracapsular surgery, and the surgeon separates the entire lens mutually with the encompassing capsule. This technique needs the IOL to be inserted in a different location, in front of the iris.

Early symptoms of cataracts involve blurred vision, glare, and stress on the eyes while reading.

• Treatment for cataracts is the operational removal of the cataract with the implantation of an artificial lens.
• Several kinds of intraocular lens types can restore vision in varying ways.
