Is the refractive surgery a risky thing to do?

No

Cornea
unless you are a poor candidate (various reasons). if you have a stable low amount of a simple, regular refractive error with a normal thick cornea and a healthy eye plus informed reasonable expectations, then the risk is small.

What are advantages of Refractive surgery prk?

No flap

Refractive_error
The advantages of PRK over LASIK are that it can be performed on thinner corneas as there is no flap to be cut. This also removes some possible complications. The down side is longer visual recovery and some post-operative pain. Consult a refractive specialist in order to see which procedure is best for you.

Tell me about Icl vs lasik - refractive surgery?

Cornea vs Lens

Lasik
Refractive surgery by sculpting the cornea to a perfect shape is achieved by the EXcimer Laser (Lasik) while correction of Refractive error by adding a permanent contact lens(ICL) on the natural lens in the eye ( Lens Augmentation procedure- Gulani AC) is done when teh corneal surgery is inappropriate for that case ie. Thin cornea etc

Dr. Richard Witlin answered:

Can you have refractive surgery on a 12 year old?

Not usually

Refractive_surgery
Most ophthalmologists want to make sure that your prescription is not changing before proceeding with refractive surgery. That is not the case for a 12 year old. Most people do not have a stable prescription until they are at least 18, maybe even a bit older.

Can vision worsen after laser refractive surgery?

Yes

Vision
LASIK generally gives excellent vision after the first week of healing. But this is a biological system and the tissues can modify over time. We call this regression and it usually adds some degree of myopia over time. For those in which this happens, it is usually minor but if it is significant, an "enhancement" procedure can be done to reverse the regression. Discuss with your LASIK doc.

What is the recovery time after refractive surgery?

1-2 weeks

Refractive_error
With Lasik, the most commonly performed refractive surgery, the vision is better even after one day. However it takes a week or two to heal.
