Ready To Get Rid of Glasses Now

LASIK is a short form of Laser in Situ Keratomleusis and it is a method to correct vision and this procedure is performed by using Excimer laser. This laser assisted procedure helps to heal nearsightedness, farsightedness and astigmatism, by reshaping the cornea of the eye. Initially, LASIK procedure is started by using a femtosecond laser by creating a thing cornea flap, by this laser operated for a few seconds. The operation of excimer laser is according to the pre-programme set in the computer and this program is written according to the correction required for the LASIK patient. This laser rapidly emits cool ultraviolet light, which removes minute tissues from the cornea’s internal part. Then the curvature of the cornea is corrected through short laser modulations, so that images will get focused over the retina clearly. The final flap created would then be preened back to the previous and original place of it and it fastens back quickly in just 4 to 5 minutes and smooth intact surface would be rebuilt.

The eligibility to undergo LASIK and get the correction of vision can be determined on the basis of the results obtained after a pre LASIK evaluation. The condition of each and every eye varies and each eye requires unique and careful examination by making use of the best technology. There is a protocol to determine eligibility for LASIK surgery and according to it, the ophthalmologist conducts a 27 point evaluation, which takes from 2 to 3 hours, for determining whether the patient is eligible to undergo laser vision correction procedure or not. One has to note and remember that every individual is not eligible for LASIK surgery, however some basic conditions for eligibility include as the following.

1. Minimum 18 years of age
2. A healthy cornea
3. No eye diseases to be existing
4. Best corrected specifications of vision, having minimum of 20/40
5. Consistent prescription for eyeglasses for at least 2 years

To undergo LASIK vision correction procedure, the minimum age required is 18 years, according to the FDA, though maximum age is not specified by it. However, the maximum age is usually recommended by ophthalmologist after examining health of the eyes and overall health of the patient and ensuring that the difficulty of vision is not because of any eye diseases or cataract. The basic and significant condition is that vision consistently has to be stable, before undergoing LASIK. Once LASIK treatment is over, the need for using reading glasses is again dependent on the age of you.

LASIK is approved to be a safe and effective procedure, though this procedure is not suitable for every individual. Some of the individuals are not suitable for LASIK procedure and in case they undergo this procedure, the outcomes would be less optimal. Hence, suitability for LASIK procedure is determined through conducting a pre-Lasik operative exanimation.

LASIK surgery is quite painless and so it does not hurt. No pain is felt because anaesthetic drops are applied in the eye, for numbing the eye entirely, during the procedure. And the laser focused on the eye causes sensation of a little pressure in the eye and once the surgery is over, the patient senses binding or gritty within the eyes and most of the patients don’t experience considerable pain. After the procedure, the ophthalmologist prescribes pain relieving medication to be taken along with considerably long rest.

This question is most frequently and commonly asked by most of the potential LASIK patients and the refractive error corrected by LASIK procedure should last for the entire life of the patient. According to the medical researches conducted and documentation, the layer of cornea, once reshaped or modified, it tends to continue to be at the same modified shape permanently. Hence, the outcomes after LASIK are almost permanent and continue for very longer time. While most of the corrected refractive errors of the eye continue to stay modified and continue to provided improved focus, in certain rare instances, regression cases are possible and it can still be corrected with enhancement surgery. LASIK has been considered to be effective and safe surgery and it is proven to be the best alternative to removal of the glasses, according to the FDA. LASIK procedure is approved to be used by NASA, Air Force and Navy professionals. The current LASIK technology in Delhi stands as a best and reliable alternative for glasses removal and approved to be safe, finest and reliable by the FDA.

LASIK is a cosmetic procedure, which is simple and painless. It takes only 10 minutes time maximum, on an overall, for both the eyes. Making usage of the laser takes only 20 seconds to 50 seconds and this duration depends on the required amount of correction according to the prescription. But, you should schedule to reach the LASIK medical centre at least one and half hours before, on the day of the surgery. The patient can have close to normal vision without glasses, immediately after the LASIK surgery.

LASIK laser eye surgery procedure is an accurate procedure and the same has been approved. However, this accuracy is highly dependent on the pre-LASIK assessment of the eyes. As newer and newer technologies are evolved and introduced for LASIK surgery, there have been newer and various categories formed and predictable, accurate and precise outcomes are now possible.

Before one day of the LASIK surgery, all kinds of contact lens wear have to be stopped. And the contact lens users, who use hard, semi-hard or RGP lens must stop using them for minimum of 2 weeks before the surgery. The users of soft contacts must stop using them at least one week prior to the procedure. Stopping of contact lens is important before the surgery as they are worn, physically over the cornea and tend to change the cornea’s shape slightly, however, this change is enough to affect and degrade the surgery results. And on the surgery day, perfume, hair-care or make-up products should not be used, as the vapours emitted by the same products can interfere the laser, which is very sensitive. You should also bring someone to accompany on the day of surgery, because you cannot drive immediately after the LASIK surgery, as blurry vision disturbs you to drive.

There has been an immense advancement taken place in the technology of LASIK, right from the basic standard Lasik technology to today’s Advanced Aspheric Lasik through Customized Lasik technology, in a period of 20 years. Some of the better technologies launched towards making flap with finest quality, in the recent few years are SBK LASIK technology and Femtosecond (iFS ^TM ) LASIK with blade free technology, which eliminate the complications, allowing better outcome after the procedure. Thin flap LASIK is always a better option, as it offers better strength to cornea. It is because thin flap can leave better ground and wider surface to perform correction of the refractive error during LASIK. Conventional flap Lasik is almost the same as this thin flap Lasik with only difference being the thickness of flap. Hence, if one cannot afford to go for thin flap Lasik, conventional flap Lasik is recommended, based on the factor of affordability. But still in certain cases, where the thickness of cornea is not adequate to undergo Lasik, the only solution remains is thin flap Lasik.

Basic vision recovery after the surgery takes from one day to one week. Most of the patients resume their day to day activities and get back to their routine and normal lifestyle after a day or two, post the procedure. And complete stability can be obtained in a month or two. Though this period varies from patient to another, most of the patients of Lasik can achieve the vision needed for legal driving or even better vision, on the day after the surgery. This is the advantage of the Lasik surgery and why most of the eye patients are inclined to this procedure as they can get back clear vision very quickly. The vision starts improving gradually day by day.

Getting concerned about the possible risks and complications after a surgery is quite obvious. Well, Lasik surgery is performed with standard protocols and experienced ophthalmologists and so far no case of loss of vision is reported or found because of Lasik or other refractive surgery. Lasik procedures make use of the Excimer laser, which is pre-programmed according to the prescription and specification of the treatment and is totally controlled by computer. Technically, there can be secluded possibility of loss of vision because of infection or inflammation of cornea and it is completely taken care through maintaining sterile conditions in the setup of laser, immediately by the surgeons and also by prescribing related medicinal drops for one week after the procedure. Apart from that you would be informed about the risks and complications possible, after pre-Lasik evaluation, during counselling. Technically, potential risks possible after Lasik surgery are too much sensitivity to light, hazy vision, infection, dry eye, pain or discomfort and problems associated with corneal flap healing.
