Preoperative investigations:
Measurement of best uncorrected and corrected vision
Analysis of tear film and production
Undilated and cycloplegic refraction
Corneal topography and pachymetry
Intraocular pressure determination
Dilated retinal exam
LASIK Procedure
You should arrive approximately 30 minutes prior to the procedure. You will be placed on a comfortable bed and given numbing eye drops. The area around your eye will be cleansed by an anti-infective wash. The eyelid lashes will be taped back with sterile tape and a lid speculum will be used to retract the lids for maximal exposure of the eye.
A special instrument called a microkeratome then creates a corneal flap, which is folded back to allow precise laser reshaping of the cornea. The flap is then reseated and securely seals within two minutes. Proper flap alignment is verified and the patient is sent home to rest for a few hours. Most regain functional vision later that same day and can return to normal activities the following day. The entire procedure averages ten to fifteen minutes total time for both eyes.
LASEK procedure
Although similar in spelling, LASEK and LASIK are not similar procedures. PRK or LASEK are effective alternatives to LASIK for specific cases in which corneal tissue needs to be spared (i.e. thin corneas.) Patients should be aware of the post-operative discomfort and delayed visual recovery with LASEK. During a LASEK procedure, a much thinner layer of the cornea is folded back to allow the laser to focus on cornea reshaping. The flap is then replaced.
Implantable Contact Lens
The implantable contact lens (ICL) is placed behind the iris and in front of the natural lens of the eye. The ICL provides permanent correction of moderate to severe nearsightedness (myopia). The ICL also contains an ultraviolet light filter.
The best candidates for the ICL are between the ages of 21 and 45, with moderate to severe nearsightedness.
Advantages of an ICL
Expanded range of treatment. Higher levels of nearsightedness may be easily treated and managed.
Patients who are not candidates for LASIK may be eligible for an ICL.
FDA studies show a high level of safety and visual satisfaction with the lens.
The ICL compares favorably with LASIK and offers a more rapid return to functional vision.
The ICL is reversible and does not remove tissue thus permanently altering the eye's shape as LASIK does.
ICL Procedure
The ICL is performed on an outpatient basis, meaning the patient has surgery and leaves the same day. Numbing drops are administered, assuring the patient's comfort throughout the procedure.
