LASIK is a type of laser eye surgery that is used for correcting vision problems. The term is an acronym for the medical term, laser in-situ keratomileusis. This type of advanced vision treatment is often recommended for people who suffer from an astigmatism, or who are farsighted or nearsighted. If your nearsightedness is advanced, then this type of treatment may not be advised.
The main goal of LASIK surgery is to correct issues with focussing. Therefore, people who take advantage of this treatment can reap a number of benefits. These benefits include the following:
- Most vision corrections are made by using this treatment approach.
- The surgery causes little in the way of pain or discomfort.
- The vision is enhanced shortly after the treatment. In fact, patients see improvement almost immediately.
- The downtime is minimal. Normally, recovery is fast and no stitches or bandages are needed.
- Any adjustments can be facilitated years after the patient has had the surgery.
- Most people who undergo LASIK no longer have to wear corrective eyewear.
A Technical and Complicated Surgery
Despite the above benefits, you still have to consider some of the drawbacks. For example, when you learn more about LASIK in Singapore, you may find that any alterations to the cornea cannot be reversed, or any further corrections can only be made by having the surgery. The eye surgery is also complicated from a technical standpoint. For instance, in rare instances, surgeons may permanently affect the vision when cutting the flap in the cornea.
Rare Side Effects
However, with that being said, most people come away from the surgery much happier about how well they can see. Again, the need for corrective lenses is removed when people undergo this procedure. Some of the people who opt for the surgery may experience a bit of discomfort shortly after the procedure. Rare side effects may include difficulty driving at night, dry eyes, glare, or seeing halos around objects.
What Happens during a Consultation?
Before you undergo LASIK eye surgery, you will meet with an advisor to discuss what to expect during and after the process. During this appointment, the vision specialist will review your medical history and your eyes will be examined. Tests typically include measuring the thickness of the cornea, as well as measuring pupil dilation and refraction. When you meet with the surgeon, be sure to ask specific questions or express any concerns you may have about the procedure.
Important Considerations for Contact Lens Wearers
If you happen to wear contacts lenses, most lenses cannot be worn for three days before the surgery. If your contact lenses are of the rigid gas permeable type, you must refrain from wearing these aids three weeks prior to LASIK treatment. If you wear eyeglasses, you should bring them with you so the surgeon can review the prescription. On the day of surgery, patients can normally eat a light meal and take any prescribed medicine. Female patients should not wear any eye makeup.
During the Procedure
During the surgery, an instrument known as a microkeratome is used to cut a thin flap in the eye’s cornea. The cornea is peeled back and the tissue is reshaped with a laser. The procedure only takes about ten minutes to complete.
