Refractive surgery FAQ,S
How do I prepare myself for the first consultation?
If you wear contact lenses, you will need to leave them out for at least 1 week for soft lenses, and 2 weeks for hard or gas permeable lenses prior to the pre-operative consultation to prevent corneal war page from affecting the measurements.
What range of refractive errors can be treated?
In general, myopia up to -15.00 diopters (1500 degrees). Astigmatism from -0.50 diopters (50 degrees) to -4.00 diopters (400 degrees) and hyperopia from +1.00 diopters (500 degrees) can be treated. The actual amounts that can be treated will depend on the individual’s eye characteristics.
If I am pregnant, can I still go for laser vision correction?
It is not advisable to have laser vision correction if one is pregnant. This is because there may be some changes in the shape of the cornea during pregnancy as a result of the hormonal changes that may affect the result of the treatment. Laser vision correction is not known to harm the unborn baby. Surgery can be considered after delivery and when your menstrual cycle has resumed. Patient should also not be breastfeeding.
What may be the side effects that I might face? Will I go blind if it blind goes wrong?
Common side effects are dry eyes. Light sensitivity, glare and halos during the first few weeks, most will subside over times. Blindness could occur if a serious complication such as infection or scarring occurs. However, this is very rare. Antibiotic eye drops are prescribed as a routine to prevent infection. At Dhami Eye Care we are performing laser vision correction since 2002. Our surgeons and staff are all highly trained and experienced to provide a safe environment for your PRK or LASIK surgery.

In some, but not all cases, contact lenses can also be used. It may be possible to wear contact lenses in all cases as the shape of the cornea has been changed by the laser surgery.

PRK takes about 5 minutes and LASIK takes 10 to 15 minutes to perform. It is done as a day surgery (outpatient) procedure without the need for admission to hospital.
Will I suffer any discomfort or pain?
The procedure is performed using anaesthetic eye drops so there is no pain during the procedure. However, you may experience same eye discomfort and tearing during the first 24 hours after the surgery. It will gradually resolve by the second or third day.

For LASIK, usually within 24 hours, most patients will experience better vision, which will gradually improve over the next few days. For PRK, the surface of the cornea takes 3 to 5 days to heal and vision will improve thereafter. Stability of the vision attained in 1 to 3 months.
Can both my eyes be operated on at the same time? If not, when can I have the other eye done?
Yes. However, it may be advisable for some patients especially those with high degrees to operate on one eye at a time. The second eye can be done as soon as 24 hours after the first eye.

For contact lens users, you can wear your lens in the unoperated eye until 3 days prior to the surgery of your second eye. You should able to cope for a short period seeing with the operated eye until the day of surgery for your second eye with no ill effects to either eye. For those who are wearing spectacles, do not attempt to remove the spectacle lens from the side of the operated eye because you will have difficulty seeing and balancing the vision. It may be easier to continue wearing your old spectacles or none at all until your second eye is operated on.

What happens if my vision is not fully corrected after the procedure?
In some cases with under-correction or overcorrection after the initial laser treatment, enhancement surgery can be performed. This can be done 3 months after the LASIK procedure or 6 months in the case of PRK. This time interval is to allow stability of the refraction to be achieved before enhancement surgery is performed.
How long will the corrections last?
Laser vision correction is permanent. There may be fluctuation of vision in the first 3 to 6 months while the eye is healing. Thereafter the result will be permanent.
