Laser-In-Situ-Keratomileusis or laser eye surgery is a ground-breaking technology that partially or totally discards the need to wear contact lenses or glasses. It works by rectifying long or short sightedness by restructuring the cornea. It is an easy, out-patient procedure that has been admired by several famous personalities such as Jonathan Edwards as well as surgeons of different niches such as Norman K Poppen MD.
This is due to the fact that the patient can go home on the same day and can resume work within a week to enjoy permanent aesthetic and practical benefits. However, you need to find out whether LASIK is suitable for all, are there any risks, and what the likelihood of success is for the people of different age groups.
Eligible Candidates for LASIK
LASIK aims to treat short as well as long sightedness along with astigmatism. But, it is not suitable for combating age-related long sightedness because the root problem lies in the lens, not in the cornea. Usually, people of over 21 years are considered as eligible for this treatment. This is because until this age, it is believed that the sight changes continue to take place due to which there is no stability. Further, the patient should not have diabetes or conditions affecting the immune system. Moreover, the surgery is also not meant for pregnant or breastfeeding women.
Types of Laser Eye Surgery
Although there are several types of laser surgery for eyes, all of them are divided into two main groups: LASIK and PRK. However, all theseÂ techniques follow the same technique of using the anesthetic drops for numbing the eyes and restructuring the cornea with a laser. Listed are the types of laser surgeries for eyes.
- LASIK: Cuts a flap in the cornea front, reshapes the causal tissue by using a special laser, and restores the flap for healing. The procedure is painless for a majority of patients and is effective immediately.
- Photo Refractive Keratectomy (PRK): Scuffs the corneaâ€™s outer layer and reshapes the left over surface. The procedure takes time to recover, and that it is more unpleasant than LASIK. Further, it does not seep deeply into the cornea, which can trigger some complications.
- Laser Assisted Sub-Epithelial Keratomileusis (LASEK): Utilizes alcohol to soften and discard the outer cornea layers and reshapes the underlying surface with laser before restoring the removed layers. It is an advanced form of PRK.
Although not serious, there are a few common but embarrassing and short-term side effects that one can tend to experience.
- Dry eyes because the nerves tend to grow again, which may stay for some months but can be treated with artificial supplements
- Blurry vision
- Droopy eyelids
- Halo effect at night, which can remain for a year
- Light sensitivity
- Pink or red patches in the white area of the eye
As per the extent of the rectification, you may be suggested not to drive for some weeks initially after the surgery because of the risk of vision. Furthermore, you will be also asked to protect your eyes by using UV protective glasses for a few months initially. Despite side effects, the surgery has been proven successful and safe for millions.
- Cornea infection
- Under or over correction of vision
- Temporary effects of surgery (loss of effects in some time)
- Excessive corneal haze or thinning of eye wall due to which the eyes can lose focus and shape
On an average, these effects of the eye laser surgery take place in not more than 5% patients.
