Cataract surgery involves the removal of the lens which is cataract affected and replacing with an artificial lens called intraocular lens or IOL to restore clear vision. Cataract surgery involves using a high-frequency ultrasound device which breaks up the protein lump that is cataract and the lens into pieces and is gently removed by suction out of the pupil and out of the eye. Once the pieces of the lens and cataract are removed, the surgeon inserts a clear artificial intraocular lens and is positioned in place behind the iris and pupil. Finally the incision site is closed and a stitch may be needed or may not be needed, a protective gear is placed which acts as a shield in front of the eye for protective purpose.

Symptoms of Cataract

Blurring of vision, light may suddenly become more sensitive to feeling, fuzziness of vision, multiple or double vision, night you may find it more difficult than before to see things, repeatedly need to change the glasses trying to correct the vision most of the times less than a year, can be some of the symptoms of cataract.

Cataract Surgery

Cataract is condition of eye lens where the lens is covered with a film of which is opaque thus clouding of the transparency of the lens, this white film is usually protein lumps formed as the age progresses in an individual. This cataract requires surgery for correction as this is not corrected with medication or with glasses. If not corrected this white lumps transform into yellow colorations and resulting in increased opaqueness and resulting in complete loss of vision.

Nuclear cataract

Nuclear as the name suggests tiny, so a tiny formation at the centre of the lens. Initially, that cataract may cause an increased clarity in the reading sight but this is a discrepancy and later on it turns out ugly by forming cloudiness of the eyes and vision and the colors cannot be distinguished adequately.

Cortical cataract

Opposite to nuclear cataract this cataracts covers the periphery of the lens. So a cloudiness is formed around the outer edge of the lens cortex and overtime this extends towards the centre of the lens as in nuclear cataract . Patients with diabetes can more likely acquire this.

Posterior subcapsular cataract

Here the lens is affected in its back and the progresses is fast compared to above mentioned types. Reading is impaired, bright light is sensed with reduced vision reduces your vision and glares the eyes and there are halos is formed around light source at night. Patients with diabetes, Uveitis and on steroid for extended period of time have higher risk of acquiring this type of cataract.

Congenital cataracts

Cataract by birth is congenital cataract, often both eyes are affected. This cataract is most of the time genetic disorder, but can also occur due to infection, trauma, inflammation, metabolic problems or drug reactions. These cataracts may be extremely small and don’t always affect vision. However, moderate to severe cataracts that affect vision may need to be treated with cataract removal surgery at the earliest to avoid lazy eye (Ambylopia).

Traumatic cataract

An injury to the eye can also form a cataract, the injury can occur on different events like driving, playing, or any other form of accidental incidents where a blunt force is involved to the eye can also cause cataracts as there is a damage to the lens within the eye.

Radiation cataract

A radiation therapy for any ontological conditions can cause cataract formation after the treatment as the lens cells are affected and damaged due to the radiation treatment.

Diagnosing Cataract

Several tests may be performed to diagnose the cataract some of which are:

A chart is used to check the reading vision of the eye with large to very small letters are used to determine the extent of visual affected due to cataract.

A microscope used to examine the eye structure in the front after magnification is called a slit lamp. The slit lamp exposes tiny abnormalities of the eye.

A dilated retina with the pupil wide open can make examination of the eye more easier. Then the doctor uses ophthalmoscope to examine the lens for evidence of cataract.

Even if your vision is clear and healthy, make it a priority to schedule yearly eye exams. Routine visits allow your eye care professional to look for signs of cataracts, glaucoma, macular degeneration, and other vision disorders. This early detection just may save your sight!


Usually if both eyes develop cataract they are not progressive with same intensity or quantity or pace so one highly progressed eye can be taken care of first or if situation warrants and both eyes need care at the same time then both can be treated with the procedure at once.

With good care and post-procedural protocols followed properly, the risks are minimal as these operations here at Harsha Sai Eye Hospital are handled with experts, but nevertheless some very few can develop post-surgical bleeding, swelling, inflammation, glaucoma, drooping eyelid, dislocation of an artificial lens, secondary cataract, or retinal detachment, etc.

Local anesthetic is administered during the surgery so yes, the person remains awake during the cataract surgery.

IOLs can be chosen best on one aesthetic criteria that is if you do not mind wearing spectacles after cataract treatment, then a monofocal lens implant can be used as it is relatively inexpensive. Generally, people require glasses only for reading purposes after the surgery. If you care to not wear the spectacles then better to opt for the multifocal or trifocal lenses.

Blurred or foggy vision, rapid sight deterioration, problem seeing during night, glares at times can be few symptoms of cataract.

Age is a factor but not always, above age 45 years can develop some form of cataract but not all require surgery and not all cases can be above 45 years there are children who can develop cataract. So the question below.
