Frequently Asked Questions
Lasik
What is LASIK, and how is it done?
LASIK is a surgical procedure that is capable of correcting a wide range of nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. For more information, please see our Step by Step section.
What does the name of the LASIK procedure mean?
LASIK is the acronym for laser in situ keratomileusis, sometimes referred to as laser assisted in situ keratomileusis. The name refers the use of a laser to reshape the cornea without invading the adjacent cell layers. In situ is Greek for “in the natural or normal place.” Medically, in situ means confined to the site of origin without invasion of neighboring tissues. Kerato is the Greek word for cornea and mileusis means “to shape.”
How long has LASIK been performed?
LASIK has been performed internationally for approximately 10 years. It was first performed in clinical trials in the U.S. in 1995. It is important to note that the major components of the procedure have a long history. Ophthalmologists have been reshaping the cornea for over 50 years, creating a protective layer of tissue for over 35 years, and using the excimer laser since the 1980s.
Who can LASIK benefit?
LASIK can benefit a great number of people with myopia, hyperopia and astigmatism. Candidates should have a strong desire to be less dependent on corrective lenses, have established realistic expectations, and understand the risks associated with the surgery.
Who can't have LASIK?
There are a number of factors that doctors must evaluate before they can determine who is an eligible candidate for LASIK. Some doctors deem certain pre-existing conditions contraindications to the procedure and will not perform surgery if you possess them. Sometimes, factors exist that preclude a patient from being an ideal candidate for LASIK surgery. In many cases, a surgeon may still be able to safely perform the procedure, given that the patient and physician have adequately discussed the risks and benefits and set realistic expectations for results.
If I'm not eligible for LASIK, are there other options available to me?
LASIK is only one type of refractive surgery available to patients. Although you may not be eligible for LASIK, you may be eligible for a different procedure. You would need to discuss your options with your ophthalmologist.
Cataract
How do I know when have a cataract?
The most common symptom is blurred vision. As the cataract develops, the progressive clouding can make night driving difficult by intensifying the reflection of lights. Symptoms differ from one person to the next. It depends on the type of cataract and how far it has progressed.
Can I have any other treatment for cataract?
Diet, medicine, eye drops or exercise have not been shown to retard or prevent the development of cataract. A cataract does not result from using the eyes too much, or by reading in bad light.
When should I operate?
Ideally with modern methods, cataract can be removed at any stage, but it should be operated when it interferes with your daily life.
Should I wait till the cataract advances or matures?
With the modern technique of ?Phaco?, the cataract needs to be broken inside the eye. As the cataract advances it hardens making it difficult to remove by Phaco. Over-matured cataract can burst in the eye and result in complete loss of vision. Thus Phaco surgery needs to be done while the cataract is still soft.
Which is a good technique for surgery?
Phacoemulsification is a good technique with advantage of micro incision, no stitches, safer and faster recovery.
Which is a good lens?
Foldable lenses are good as they can be inserted through micro incision requiring only a small puncture. With advance optics foldable lenses the quality of vision especially at night and low light conditions is much better.
