Safety And Precision In LASIK With The Wavelight 500HZ Wavefront Technology



LASIK an acronym for LAser in SItu Keratomileusisis is a process of re-shaping the external area of the eye [the cornea] to suitable lower, average and higher degrees of nearsightedness, astigmatism and significantly-sightedness. With this strategy one receives rid of their spectacles or call lenses. It has been practiced in our place for the last 6 to 7 several years. The most up-to-date advancement in the LASIK method is wavefront-guided LASIK. Wavefront strategies really often go away clients with eyesight far better than ordinary. In addition the ideal candidates are inclined to be those who have gone through more mature techniques of vision correction and have been dissatisfied with the final results.


Like our fingerprints, just about every of our eyes is different and has its personal distinctive condition and visual attributes. Wavefront Guided LASIK develops individualized computer software treatment designs for each individual eye. Not like the typical LASIK course of action which only corrects refractive glitches (myopia, hyperopia and astigmatism) and routinely achieves 20/20 eyesight, Wavefront LASIK goes past just correcting refractive mistakes to really improving upon visual capabilities so you may well see improved than you did with eyeglasses or lenses in advance of the method, that’s why strengthening your ‘Visual Acuity’.
The visual process is really able of looking at 20/10 or superior, that is letters twice as smaller as the 20/20 letters on an eye chart. Most individuals are not able to see beyond 20/20 for the reason that of pretty refined imperfections inside their visible program. Using the Wavefront technological know-how, it is attainable to initially map these delicate visible imperfections and then build a laser treatment prepare to right them.
The key to Wavefront treatment is a product named a Wavefront Analyser or aberrometer. This initiatives a high-quality grid of 168 light beams onto the retina and captures its picture applying a high resolution CCV digicam. This image is then compared with a single from a usual eye and the difference in between the two presents a “Wavefront Map” which is utilized to program the laser.

This implies we can evaluate each the extent of bad eyesight and its leads to with higher precision than it has ever been attainable right before.

With conventional techniques there could be scenarios of unpredictable effects where by refined interior optic mistakes, alternatively of getting dealt with, are even more magnified. This may guide to dissatisfaction immediately after the normal method of LASIK. With wavefront LASIK these faults can be corrected to reach perfect effects.


Some of the common explanations why men and women undergo LASIK are due to the fact of call lens intolerance, cosmetic factors, social (relationship), worn out of donning eyeglasses, and life-style actions that are inhibited thanks to eyeglasses or lens have on such as outdoor sports like golfing, football, water sports activities or climbing. Spectacles are cosmetically unappealing for some. There is a diploma of distortion when seeking by means of the periphery of the eyeglasses, the industry of eyesight is reduced and on leaving a chilly home moisture can fog the glasses and blur eyesight for a couple minutes. Hence glasses are unacceptable for certain careers this kind of as the Army, Merchant Navy, Airlines, Air Force, Railways and expert athletics. Make contact with lenses require notice to cleanliness all through insertion and elimination failing which sight-threatening infections may well result.
Wavefront LASIK overcomes all these shortcomings.
With Wavefront guided LASIK it has now turn into possible to handle a bigger spectrum of clients. This treatment particularly helps to have obvious eyesight in dim mild, which would have if not been challenging with the more mature methods. On top of that, all those who have been disappointed with any form of vision correction are candidates for Wavefront guided customised remedies.


The cornea is preferably intended to have a smooth curvature. The incident gentle falling upon it is in the variety of a clean curve, referred to as a ‘wavefront’. As this smooth wavefront courses by way of the different elements of the eye and their imperfections, ocular aberrations are induced, which degrades the retinal impression good quality. An aberration-totally free eye would end result in a easy wavefront image on the retinal surface area, achieving the ideal optical excellent and ‘supernormal’ eyesight that is usually considerably superior than 6/6. Wavefront-guided custom-made LASIK, also referred to as ‘customized ablation’ performs corrections centered on specific wavefront measurements, which perhaps will increase the odds of greater than standard vision.

Positive aspects OF WAVEFRONT- GUIDED LASIK In excess of Typical LASIK

New scientific tests point out that

o 100% individual fulfillment with insignificant aspect effects or troubles.

o 70% of these people received one to two lines of visible acuity additional than what was envisioned from this cure before the method.

o 16% of wavefront-guided LASIK people realized a publish-method uncorrected visible acuity of 6/3 [3 lines smaller than normal].

o Wavefront cure benefits have been uncovered to provide secure, accurate article-operative final results.

o The incidence of publish-operative indications such as glare, haloes, decreased distinction sensitivity and inadequate evening eyesight as with regular LASIK are commonly absent or tremendously minimized with wavefront treatment options.

o Wavefront-guided remedy has apps in difficult submit-refractive surgical procedures (RK, PRK, LASIK) people (with sizeable signs, decentred treatments) as very well as in clients professionally requiring acute vision.

Features OF AN Great LASER

The WaveLight is the greatest laser for wavefront processes making use of the fastest and most sensitive eye tracker in the globe [500 Hz] to make sure beautifully exact and perfectly-centred treatment plans.
This laser has the fastest cure time [500 Hz], an important aspect in guaranteeing uniform cure above the whole surface area of the cornea by reducing dehydration of the cornea and other exterior influences throughout the treatment. Also the Concerto customizes corneal form not only to boost visual acuity but also to boost distinction in particular in dim mild problems.
The extremely sophisticated WaveLight laser makes use of a ‘Flying Spot’ of .9 mm, a requirement to allow for precise placement of laser remedy. This precise cure leaves practically nothing to luck or chance. Wavefront techniques extremely often leave patients with vision far better than ordinary [super – vision or eagle vision].

The WaveLight Concerto saves upto 40% of precious corneal tissue for every dioptre of therapy when in comparison with other lasers. This final results in the health practitioner remaining equipped to take care of a higher electrical power assortment retaining in mind extended-time period security as perfectly as treating reduce powers with unmatched security.

Food and drug administration COMPARISON OF EXCIMER LASERS

In the comparison higher than, that the complaints of glare, night eyesight problems and fluctuations are quite superior [upto 50% patients] in just one laser [Nidek], when in the rest these are really smaller and in the Wavelight it is nearly negligible.

In this comparison, one can see that as the refractive power [spectacle number] receives higher, the results of precise 6/6 normal vision drop down with most lasers but the Wavelight results keep on being earlier mentioned 90%. These outcomes are with the before generation of the Wavelight laser ie. 200 Hz. The most up-to-date laser of 500 Hz is even more correct.

Evaluation OF A Candidate FOR THE LASIK Treatment

A full eye assessment is essential to check a patient’s suitability for LASIK.
Tests contain refraction, contrast sensitivity, pupil size, pupil response, retinal evaluation, tonometry, pachymetry, aberrometry, topolyzer measurements, topography and checks for dry eye amongst some others. Client counseling is a really substantial component of the pre treatment get the job done-up.
LASIK analysis and screening with the topography and aberrometer determines which of the two techniques regular LASIK or wavefront LASIK would utilize for the individual.

THE LASIK Technique

It is a discomfort- no cost outpatient technique that generally can take 5 minutes for every eye.
The precise laser procedure normally can take a lot less than a moment. Topical anaesthetic drops are utilized. Throughout the procedure, an instrument known as the microkeratome results in a corneal flap. The computerized Excimer laser employs a interesting beam of mild to gently reshape the cornea so as to change its curvature to the ideal extent. The flap when changed on the new corneal curvature makes it possible for images to be sharply concentrated on the retina. A put up-course of action eye assessment with the slit lamp is executed and eye drops are prescribed.


An improvement in vision is observed in just 4-6 several hours with restoration of functional vision by the following early morning. Full recovery may well acquire upto 48 hours.


LASIK is Harmless when performed on a suited prospect with most of the new generation Excimer lasers. Wavefront-ready lasers are extremely refined. Hundreds of thousands of sufferers worldwide, who are Indian by origin, have experienced LASIK finished on them efficiently.


The mix of a remarkably advanced technology, using a laser that delivers the physician and the affected individual the highest stage of safety, precision and dependability in LASIK together with the surgeon’s experience, done underneath Intercontinental protocols and with International criteria of cleanliness is what achieves superb success!
