What is Lasik?
LASIK (Laser-Assisted in-Situ Keratomileusis) is an out-patient procedure that involves the creation of a micro thin corneal flap and the use of a laser to reshape the cornea of the eye. This flap can be created in two ways: with the use of a microkeratome blade or with the blade-free IntraLase™ Femtosecond Laser.
Lasik surgery is used to reduce or eliminate the use of glasses and contact lenses. It also helps to treat, improve and correct vision problems such as myopia (nearsightedness), hyperopia (farsightedness), presbyopia (blurring of vision due to aging) and astigmatism (images appear blurred and distorted.
LSC Philippines specializes in Lasik refractive surgery and takes pride in using only the most trusted excimer laser worldwide, the VISX™ Star4 Excimer laser with IRIS registration and the latest and most up-to-date blade-free, IntraLase™ Femtosecond Laser. These technologies are used to treat US Top Gun pilots, Navy SEALS and NASA astronauts and are capable of performing precise customized treatments that can improve vision beyond 20/20.read more

Suitability of Candidate
LASIK is not for everyone. The ideal candidate would have a good overall health status because various conditions can slow down the healing of the cornea after LASIK surgery. These include auto-immune conditions as well as those that require medication that slow down the healing process. Slowed healing whether by condition or age can increase the likelihood of complications to develop.
Pregnancy is a phase that is also not ideal for LASIK surgery. This is because eye shape can be temporarily altered by the hormonal changes involved during pregnancy.
Some corneas are simply too thin to undergo LASIK surgery. If too much tissue is cut in such instances, the remaining corneal tissue is not sufficient to provide integrity to the refractive process. LASIK in such cases may worsen rather than improve vision. The alternative possibility is LASEK, a procedure that does not involve a blade cutting a corneal flap.
Some corneas are too irregular in shape for LASIK to work successfully. This can arise from a condition known as keratoconus whereby the cornea steepens into a cone shape. Some irregularities of the cornea that occurs in mild to moderate levels of astigmatism are Â usually acceptable and can be treated successfully with LASIK.
Naturally large pupils may actually exceed the size of the small and circular corneal area treated by the excimer laser in LASIK surgery. This results in various visual problems like halos that can occur particularly during the night when the pupils are at their largest.
Eyes that are already considered dry by medical standards prior to LASIK are predisposed to delay healing after the surgery. The quality of vision is hence affected regardless of the outcome of the procedure. The condition of dry eyes is also a significant side effect associated with LASIK surgery. Chronic dry eyes may result from LASIK surgery when performed on eyes that are already considered dry or are likely to become dry.
The various conditions that reduce suitability for LASIK can be diagnosed and assessed by a good LASIK surgeon using specific quantitative tests.
Advances in the LASIK process are constantly expanding the scope of the procedure. Hence, some of the disqualifications to the procedure today may not be applicable in the future. Other contraindications may be circumvented by procedures like LASEK and corneal transplantation.
LASIK surgery has developed as an effective means for sight enhancement for the qualified candidate. A lack of suitability to undergo the procedure however, does not imply an end to the quest for perfect vision.read more
If you decide to go ahead with Lasik surgery, you will need to undergo lasik screening or baseline evaluation by your eye doctor to determine if you are a good candidate.
Lasik screening includes:
- Automated Refraction (AR)
- Manifest Refraction
- Patient Briefing on Lasik
- Orbscan/ Topography
- Lasik Suitability Test
- Pupil Dilation
- Lasik Counseling
- Cyclo Refraction
- I.O. / Consultation with Ophthalmologist
Kindly note that:
If you are a contact lens wearer, it is a good idea to stop wearing them before the screening and switch to wearing your glasses full-time. Contact lenses change the shape of your cornea for up to several weeks after you have stopped using them depending on the type of contact lenses you wear. Not leaving your contact lenses out long enough for your cornea to assume its natural shape before surgery can have negative consequences.
These consequences may lead to inaccurate measurements and a sub-optimal surgical plan, resulting in poor vision after surgery. These measurements, which determine how much corneal tissue to remove, may need to be repeated at least a week after your initial evaluation and before surgery to make sure they have not changed, especially if you wear RGP or hard lenses.
If you wear:
- Soft contact lenses or toric soft lenses, please refrain from wearing them for 5 days before your initial evaluation
- Hard lenses or rigid gas permeable (RGP) lenses, please refrain from wearing them for at least 14 days before your initial evaluation
