Refractive surgery is a type of surgery performed on the eye to correct vision defects. The types of defect that this surgery can correct are:
- Astigmatism – a distortion of the cornea or the lens so that light is not refracted properly. This causes blurred or distorted vision.
- Myopia or nearsightedness – people with myopic vision can see nearby things clearly, but objects that are further away appear blurred or distorted.
- Hyperopia or farsightedness – the opposite to myopia. People with this defect can see distant objects clearly, but objects that are close appear blurred or distorted.
- Presbyopia – an age-related inability to see nearby things clearly. This is not to be confused with hyperopia, which is caused by an irregularity in the shape of the cornea or lens. Presbyopia is caused by the lens becoming more rigid as people grow older. The rigidity makes it impossible for the lens to adjust to be able to see nearby objects.
Types of refractive surgery
There are several different types of refractive surgery. Your ophthalmologist will examine your eyes to determine the cause of any vision defects, and will then explain what your treatment options are. These will depend on several factors, including your general health and your age.
Among the most commonly used procedures are:
- Phakic intraocular lens implantations
These are also called implantable contact lenses. The lens is surgically implanted in the eye beneath the iris, the colored part of the eye, and in front of the eye’s lens.
- LASIK and LASEK surgery
A small incision is made in the cornea, using a laser beam or a special tool. The incision allows the surgeon to peel back a small flap on the cornea to allow access to the corneal tissue, which is then reshaped using a laser.
- Conductive Keratoplasty (CK)
This is a type of surgery used to correct farsightedness in people over 40. A probe that emits radio waves is used to reshape the cornea.
Does refractive surgery require hospitalization?
Most refractive surgery is performed on an outpatient basis. It can take up to 24 hours for vision to return to normal, so it is advisable to have somebody accompany the patient. Most patients can return to work on the day following the procedure.
