LASIK Facts

Glasses or contact lenses have become very common these days and one sees even young children with them. They are very useful, no doubt, and help restore our vision to us. However, they have many drawbacks and therefore people are always looking for ways to get better eyesight without glasses.

Contact lenses are a convenient and affordable option for vision correction. Today, patients are finding that contact lenses are becoming more and more comfortable. This higher comfort level can be attributed to advancements in a key material used in making the lenses.

Choosing the right contact for your needs is important. Many people have experienced new levels of comfort with daily disposable contact lenses due to the following advantages.

Continuous wear contact lenses are a great alternative for people who cannot function without the aid of glasses or corrective lenses. Surgery is not a viable option for everyone because it depends on their vision and health. Also many people are afraid of surgery, cannot afford it or simply don't want to have it.

Traditional LASIK surgery achieves a simple correction of focusing power by reshaping the cornea with the aid of a laser. Wavefront LASIK is a variation of that conventional procedure and accomplishes a spatially varying correction based on readings from a wavefront sensor. In essence, a wavefront sensor measures the eye itself. Wavefront measurements reveal the irregularities of the lens, which cause optical aberrations (any deviation from a desired perfect planar wavefront). Wavefront custom sculpts the cornea to accomplish corrected vision. In many ways, Wavefront offers better results than traditional LASIK. LASIK has certain potential side effects including halos or glare, which are caused due to induced spherical aberration. Anyone considering Lasik laser eye surgery will welcome the introduction of wavefront technology into the process. It gives the eye surgeon the information needed for a more effective and successful procedure. Eye surgeons now have available a new technology that makes vision correction more precise. It's called “wavefront”.

To correct poor vision Lasik eye surgery has become the popular choice. Lasik surgery links the condition of the patient's visual system to the Lasik laser for correction. The incisions performed on the cornea of the eye are customized to the patient's individual needs. Accurate data concerning the condition of the patient's eyes is all important. Wavefront technology is a technology that is capable of measuring refraction at multiple points on the eye as light is reflected upon it. This creates a “map” of the patient's eye. Because each eye is unique the data from each eye must be carefully analyzed so that the Lasik laser maybe properly programmed. Conditions within the cornea of every eye affect refraction. The ability to treat these aberrations can result in an improved outcome after Lasik surgery. Clinical trials using wavelength technology have shown that nearly 80% of Lasik eye surgery patients undergoing custom surgery achieved 20/20 vision.
