How To Relieve Dry Eye Caused By Lasik Surgery

Dry eye is a common eye problem, and there are many causes of dry eyes

, one of which is the postoperative side effect of Lasik surgery. In normal circumstances, Lasik surgery, some studies show that, is one of the main causes of dry eye, although sometimes certain people seem to experience no dry eye symptoms.

Reasons why Lasik surgery leads to dry eye are as follows. In the process of a Lasik procedure, there must be a corneal flap created by either a steel blade or a laser, during which the corneal tissue and corneal nerves are supposed to be broken up. What is more, the following reshaping of corneal by laser will come to further disrupt the nerve tissue. If the patient suffer from a comparatively more seriously eyesight problem, the nerve tissue is thought to be cut deeper, which does more side effect to eyes. Then due to the whole disruption, the nerve tissue, when recovering and regenerating, is normally hard to produce tears to keep eyes moistened. Thus dry eye symptoms emerge.

( What is more, for supplement only, whether the corneal surface and tear lay are created to be qualified or smooth is closely related to another eyesight problem of "ghosting" and "fuzziness", as when light comes into eyes, it meet with the tear layer at the very first. If the corneal surface or tear layer is of irregularity and deficiency, visual acuity will be greatly affected.)

As a surgeon, considering the possible side effects of dry eyes, and ghosting or fuzziness images creation, I advise several ways to minimize those possibilities after operation: have an overall examination concerning eyes, including the evaluation of preexisting dry problems; apply the Intralase FS lasers, but not the steel razor blade microkeratome to create the corneal flap, which is believed to be more able to minimize unsmooth and unqualified corneal surface and tear layer; after the surgery, use artificial tears and gel lubricants for a series of days. Those who do not have the experience of dry eyes after lasik surgery are also suggested to. The cyclosporine 0.05% eye drops (Restasis) are recommended.

It has been researched that the above regimens are able to relieve dry eyes, as well as other eye problem after Lasik surgery. By persisting in the regimens, improvement of eyesight, but also the prevention from secondary side effects can be guaranteed. Besides, get more information of Lasik surgery in advance is also helpful to enhance the outcomes.
