Everything You Should Know About Lasik Eye Surgery

LASIK , or “laser assisted in situ keratomileusis”, is not a specific procedure, it is a category of refractive surgeries. Often misspelled or mispronounced as “lasic” or “lasix,” there are multiple types of LASIK surgeries. Only a qualified LASIK surgeon can determine the feasibility of a specific procedure for a specific patient.

What is LASIK Surgery?

LASIK surgery is eye surgery, performed by laser, which allows correction of vision problems. The surgery is not appropriate for all patients. In all LASIK procedures, the vision correction results from a removal or reshaping of some portion of the cornea in the eye. There are five major types of LASIK, each of which may be suitable for different patients.

Custom Wavefront LASIK

In this form of laser eye surgery, special three-dimensional measurements of the eye are used to map out resurfacing the laser will perform. This is referred to as “custom” because of the highly individualized results that are not easily replicated with normal corrective procedures. Use of this type of LASIK can result in excellent vision correction with a reduced risk of negative effects.


During this procedure, a flap is cut into the upper layer of the cornea. A laser is then used to shape the cornea in the area where the flap has been lifted. After the procedure is completed, the flap is returned to its original position to allow the cornea to heal. Patients undergoing this form of surgery will likely wear contacts for the first few days after the procedure to allow the cornea to heal properly.

IntraLase LASIK

This form of laser eye surgery uses two different lasers during the surgery. Instead of creating a flap using traditional methods of cutting the flap, the corneal flap is created by a second type of laser. The use of this type of laser reduces potential complications involving the corneal flap, but this procedure may not be appropriate for all patients.


This is an advanced laser vision correction surgery which allows custom vision adjustments for seeing at varying distances. Sometimes called “multifocal” LASIK, this surgery is used to allow an eye surgeon to correct vision in part of the eye for distance, while another portion of the eye is adjusted for near vision.

Things to Consider Before Having Laser Vision Correction Surgery

The decision to have laser eye surgery should not be taken lightly. While rare, there is a possibility of severe complications. Discounted surgery rates should be carefully researched and regarded as suspicious until the patient is sure that the doctor is well trained and the lasers are properly maintained.
