Custom LASIK Surgery also known as Wavefront LASIK Surgery makes use of a three-dimensional measurements of the way in which the eye processes images, as information to rectify vision problems. This information is derived at by measuring the way in which the eye focuses on light rays. A three dimensional map is created to show how the defective eye processes image to bring out their regularities of the vision see through the eye.

This information is used to guide the laser in reshaping the cornea to remove vision defects and make way for clear vision. The main benefit in Custom LASIK Surgery is that it offers scope for more precision in vision correction, something which is not possible with traditional LASIK surgery. Even lenses and eyeglasses cannot correct vision the way Custom LASIK Surgery can.

Custom LASIK Surgery is a groundbreaking form of LASIK surgery because it help the eye to improve in terms of not just how much can be seen, but also in terms of how well it can see images. Patients experience less of complications such as halos, glare, problem in night time seeing which is often the case with traditional LASIK surgery

PRK or photorefractive keratectomy is a form of Lasik surgery, which was devised in the 1980’s, but it received approval from the FDA only in 1995. Though it came later into use as a form of corrective eye surgery in the United States, it was used pretty much in other countries.

In PRK, an excimer laser is used to remove tissue bits from the cornea surface, in order to reshape it ad alleviate vision problems. People with myopia and hyperopia can undergo PRK to rectify their vision. During surgery anesthesia is applied to remove any pain. Time taken for surgery depends on your eye vision prescription. So the higher your vision problem, the more time you need for correction during surgery.

After surgery recovery can take more time, with the recovery period ranging from weeks to a couple of months time. People who have undertaken PRK surgery are know to achieve 20/20 vision or 20/40 vision
