Lasik Surgery
LASIK is a type of refractive surgery which is done to get rid of glasses & refractive error .
Conventional LASIK uses an excimer laser to reshape the cornea so it can refract light properly, restoring clear vision.
This laser eye surgery improves the way light rays are focused on the retina. LASIK is used to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
The goal of LASIK is to correct your refractive error to improve your vision.
Who is a good candidate for LASIK surgery?
To have LASIK surgery, you need to meet certain requirements. Here are some of them:
- You should be 18 years or older (ideally, over 21 years old, when vision is more likely to have stopped changing).
- Your eye prescription should not have changed much in the last year.
- Your corneas need to be of sufficient thickness and healthy, which is decided after doing some tests ( Lasik Workup)
- You need to have realistic expectations about what LASIK can and cannot do for you.
Before the laser eye surgery
- You and your ophthalmologist will discuss your vision needs based on your lifestyle. For example, if you play sports, you may be seeking clear distance vision from surgery.
- Some eye tests are done to see if your eye is suitable to undergo LASIK procedure Test your vision. This is to make sure that your vision has not changed. It also shows how high your refractive error is and whether LASIK can be used to correct your vision.
- Check for other eye problems: such as dry eyes, lattices or weak spots in retina etc .
- Measure and map the surface of your cornea. Your ophthalmologist will check the thickness of your cornea and make precise measurements of the cornea’s surface , shape and contour (Corneal Topography ). Check if there is dryness in your eyes.Your eye surgeon uses these measurements to program the computer-based laser used during surgery.
- Vision after LASIK
- About 9 out of 10 people (90%) who have LASIK end up with vision between 20/20 and 20/40—without glasses or contact lenses.
- It is important to know that LASIK cannot correct presbyopia. With or without refractive surgery, almost everyone who has excellent distance vision will need reading glasses after around age 40.
What is Contoura Lasik?
Contoura Vision TopoGuided LASIK is a new technology designed to enhance the effects of LASIK. It corrects the vision based on the corneal topography (corneal curvature maps) as against the correction of vision in a standard LASIK surgery which is only based on glasses or contact lens prescription.
The Topolyser has unparalleled diagnostic capabilities to record even the minutest imperfections in the curvature of the cornea. It provides an incredible measurement of 22,000 points as compared to the currently available wave front-guided LASIK that measures around 200 points. Hence this technology is remarkable as it corrects the refractive errors with higher precision than ever before.
As per the clinical trials statistics, almost 90% of patients post-operatively saw as well or better without glasses than they ever did with glasses or contact lenses.
- Decrease in difficulty during night driving
- Lesser sensitivity towards light, less glare
- Better quality of vision
