About Custom Wavefront Lasik

custom-wavefront-lasik Karachi Laser Refractive Surgery (LASIK, PRK, LASIK) has effectively corrected the eyesight of more than 6 million people. An approximated 98% of traditional laser vision correction patients at present see 20/20 to 20/40 without having glasses. However, conventional LASIK can just deal with the visual distortions (aberrations) that account with regard to 85-90% of the quality of vision. Most recently, refractive surgeons have realized that there are more optical defects in the eye that impact vision and could account for such signs and symptoms as glare, aura around lights, blurry images or bad quality of vision. Such so-called higher-order aberrations can easily be detected with the help of an instrument known as a Wavefront analyzer, also recognized as an aberrometer. As demonstrated in clinical studies, this accurate level of measurement and correction enhances the prospective to attain 20/20 vision or better.

Until most recently surgeons assessed the prescription for laser vision correction utilizing precisely the same techniques which are used to recommend eyeglasses and contact lenses. The laser cured identical prescriptions really the same for all eyes. These days, Prof. Shahid Femto Lasik & Day Care Center presents the most up-to-date technology to lead our lasers to deliver a customized surgical procedure specially made for the individual eye. It notjust adjusts the error(s) coming from the eyeglass prescription, however also adjusts the higher-order aberrations that may lead to the different 10% to 15% of visual distortions impacting your quality of eyesight. We call it All Laser HD (High-Definition) Vision and then for a number of patients it can easily provide even far better results than present traditional treatment chosen by most eye surgeons.

Facts

Each of our lasers are capable of customized laser treatment. The first step is to generate a wavefront map by passing a narrow ray of invisible infrared light through the eye. The goal is to measure distortions in the eye’s entire optical system. The wavefront information is then downloaded to a floppy disk and transferred directly to the laser. At Gordon-Weiss-Schanzlin Vision Institute we have the unique ability to select the laser that has the potential to provide the best results for our patients.

At your consultation, you will undergo a wavefront and Oculus Pentacam corneal analysis in addition to other sophisticated diagnostic tests. Prof. Shahid will then base the decision regarding your treatment after a complete eye examination and analysis of your pupil diameter, corneal thickness, corneal curvature, corneal topography (shape) and wavefront analysis. You will meet Prof. Shahid at your consultation to discuss the recommendations and answer all your questions.

Customized LASIK, used in conjunction with our new ALLEGRETTO WaveLight® FS200 Femtosecond laser to create the flap, allows our LASIK surgeons maximum control and accuracy in customizing surgical parameters for each patient’s individual visual needs. The femtosecond laser was developed specifically to operate in conjunction with the Allegretto Wave ® Eye-Q excimer laser to produce flaps in approximately 6 seconds and increase patient safety and comfort. This is the only system designed for complete integration between the excimer and femtosecond lasers.

Once you are prepared for treatment on the day of your LASIK procedure, the information obtained from your Wavefront analysis is integrated with our ALLEGRETTO Wave ® Eye-Q excimer laser. The Eye-Q excimer laser is known as the fastest, most effective optical lasers available. The laser is able to follow the movements of the eye at 1000 times per second, giving your LASIK surgeon a very precise alignment of the eye’s position. Each treatment with the laser is customized to your prescription, with the aim of reshaping the cornea – as precisely and accurately as possible – to allow you to see more clearly without complete reliance on glasses or contact lenses. In some cases, this laser has allowed patients to achieve 20/20 vision or better.

The risks associated with All Laser Custom Vision treatment are the same as those with any form of laser vision correction. The ability to control higher-order aberrations and to reduce or eliminate any potential increase in these distortions makes customized laser vision correction a particularly desirable procedure. The improved software programs for All Laser Custom procedures have improved upon the excellent visual results that are currently obtained with conventional laser vision correction.
