Of the five senses, vision is the most powerful. Vision allows you to perceive the world and assess your environment with speed and accuracy, abilities that enrich experience and hasten response to danger. Seeking eye surgery that may improve visual acuity or to restore vision deteriorated from disease has obvious advantages, but be aware of possible complications.
Dry Eyes
Dry eyes are caused by a decreased production of tears to lubricate the surface of the eyes. Tears are produced by the lacrimal glands, located under the skin at the junction of the corner of the eye and upper nose. Typically, blinking spreads the tears over the eye surface. If blinking is prevented, dry areas develop on the surface of the eye that compromise vision. Tears are important to keep the eye moist, prevent infection and aid wound healing. The cause of dry eyes proceeding eye surgery is unknown. Treatment includes administering artificial tears, applying a sterile ointment--such as petroleum--to the eyes at night to prevent drying, and using a humidifier to moisten the ambient air, according to the University of Illinois at Chicago.
Corneal Ulcer or Infection
The cornea is the clear covering of the eye. A corneal ulcer or infection is a rare complication to eye surgery and can occur if bacteria, fungus, a virus or parasite gain access to the inner compartment of the cornea. The following symptoms can present: eye redness, watery eyes, pain, burning, itching and a discharge. Treatment of a corneal infection depends upon the cause; most cases begin with a course of antibiotics or antiviral eye drops, according to the University of Maryland Medical Center.
Light Sensitivity
Light sensitivity, or photophobia, is a possible complication following eye surgery. If light sensitivity produces moderate to severe pain and causes you to wear sunglasses in doors, you need immediate medical attention. Treatment of this condition involves staying out of the sun, remaining in a dimly lit room and wearing sunglasses outdoors, according to the University of Maryland Medical Center.
Astigmatism
An astigmatism is an eye condition in which the surface of the cornea has an irregular curvature that causes refractory errors. The refractory error causes the light that enters the eye to bend erroneously, causing blurred vision. An astigmatism is not a disease; it's a misshapen cornea. To correct the refractory error and blurred vision, corrective lens must be worn, according to the University of Michigan Kellogg Eye Center.
