Refractive Surgery includes any surgery that is done to reduce one’s dependency on glasses. LASIK surgery is the most common vision correction procedure all over the world.
LASIK –Laser In Situ Keratomilieusis surgery basically involves two steps- Creating a precise thickness flap on the cornea ( glass like covering of eye) and then using excimer laser to alter its shape to give clear vision without glasses. In bladeless LASIK, instead of a motorized blade, another laser called as Femtosecond Laser is used to create flap, thereby increasing safety, efficacy and predictability of the LASIK surgery.
With its excellent safety profile, patient comfort and superior visual outcomes, Blade-free LASIK is among the fastest-growing refractive surgical techniques in the country today .The procedure is a simple, painless and comfortable solution that allows the patient to adapt to a life free from glasses. The wavefront optimized platform gives best image quality with a clearer vision. The entire vision correction procedure takes less than 15 minutes in time and patients are able to resume their day to day activities right from next day.
At GUPTA EYE HOSPITAL,PANIPAT, along with providing the best in eye care, we believe educating our patients and keeping them up-to- date with modern technology that plays a key role in making your experience of surgery a painless and memorable one. Here are some of frequently asked questions for getting rid of your glasses.
Here are some of frequently asked questions for getting rid of your glasses.
1. What is LASIK surgery
In simple terms, LASIK surgery involves reshaping of your cornea (the front glass like covering of eye) using highly precise laser called EXCIMER LASER.
2. Am I fit for LASIK SURGERY?
Your Eye surgeon would first perform a detailed clinical assessment of your eyes and would recommend a test called as Topography which would enable them to decide whether you are fit for LASIK surgery or not.
Around 10% of patients are labelled unfit for LASIK surgery. That is why it is mandatory to undergo a proper pre-LASIK checkup with your LASIK surgeon.
3. Will my number become zero after surgery?
LASIK is meant to reduce your dependency on glasses, but may not completely eliminate their need. The total number of the patient is fed into a highly precise computer technology but the healing of the human eye is unpredictable. A negligible residual number may persist but this doesn’t necessarily mean that the patient requires glasses. Often patients are eager to know whether their number after surgery is zero or not, and they overlook the fact that they have completely normal vision and are comfortable with the same.
4 – Does the effect last forever?
LASIK is a laser done on the eye to reshape the cornea such that the number is minimized. However, it cannot halt your normal aging process. Presbyopia is a condition near around the age of 40 years when an individual starts developing a reading glass power. This is because of the effect of age-related changes in the eye. This effect begins around 40 years and progressively increases up to the age of 60 years. An individual who had no glasses for all his life may now require glasses for reading/ writing/ mobile phone use/ near work.
5. UPTO WHAT AGE CAN LASIK BE DONE?
I often get asked this question by the older generation. The minimum age for LASIK is 18 years with a stable number for atleast 1 year. There is no real maximum cut off age for LASIK NOW.
Now with the availability of ‘PRESBYOND’ (presbyopia LASIK) at GUPTA EYE HOSPITAL, people above 40 years of age who yet haven’t developed cataract also can enjoy spectacle free vision.
6. Alternatives to LASIK
It is important to know that not everyone can undergo the LASIK procedure. The concerned person’s eye must be of a certain curvature and thickness to permit the surgery. Beyond permissible limits, the procedure may be harmful to your eye. E.g if the cornea is too thin/ too steep/ too flat or the spectacle power is very high.
The nonsurgical options like glasses or contact lenses are always there. Always remember that Lasik is a cosmetic procedure!!
For thinner corneas, a blade-free procedure called EPILASIK or PRK ( Photo Refractive Keratectomy) can be performed. In this procedure only the uppermost layer of the cornea i.e. the epithelium is removed instead of making a flap. Since lesser tissue is involved, it may be a better option for thinner corneas. Ultimately, the laser that removes the number is the same in both the procedures. (Only the first step differs.)
For corneas that are too thin or that have very high spectacle powers, a better option called ICL can be done. This is an Implantable Collamer Lens, similar to a thin contact lens of your eye power, but surgically inserted into your eye and it rests on the natural crystalline lens.
7. Can I get permanent spectacle independence even if I am not fit for LASIK surgery?
Yes . There are special lenses that can be implanted inside your eyes safely and permanently to give you spectacle independence. These are permanent lenses which stay inside your eye and are called Implantable Collamer Lens (ICL).
8. What is the recovery time after LASIK surgery
Ans. LASIK surgery itself is a painless surgery which gets over in less than 5 minutes. The patient can get back to routine activities right from next day of surgery.
