Laser in situ keratomileusisor LASIK is a commonly performed outpatient eye surgical procedure that is used as an effective treatment for many vision problems like hyperopia (farsightedness), myopia (near-sightedness), and astigmatism. However,LASIK eye surgery cannot reverse presbyopia, the age-related loss of close-up focusing power, which mainly affects near vision. Specifically, the ophthalmologist uses a laser to reshape the cornea, the clear covering of the front of the eye. This improves the way the eye focuses light rays onto the retina, at the back of the eye, allowing for better vision.
Scheme of the surgery-
In this procedure the patient is first made to recline under an excimer laser, the eyes are then made numb with anaesthetic, a speculum is placed between the eyelids to keep them from blinking and once the patient is ready the correction process is begun.
The surgeon first cuts a flap in the stroma (the cornea’s middle layer) and then uses the laser to remove some of the tissue under the flap, reshaping the cornea. The flap is then replaced and the cornea is allowed to heal naturally. The whole procedure takes less than a few minutes per eye.
After surgery, you should avoid rubbing the eye and use an eye shield, to prevent the flap from shifting out of place.
Benefits of seeing better with LASIK-
As a safe and painless procedure it allows many people to perform most of their everyday tasks without wearing corrective lenses or eyeglasses.
LASIK eye surgery majorly involves lifestyle changes. All the advantages can be stumped into one word- Freedom. Patients are free to play, swim, dance, look through cameras or binoculars without having to take off their glasses or lens first.
However, as people age, visual acuity often continues to deteriorate regardless of corrective surgery as it only corrects vision and does not cure its underlying cause. As a result some people might again require glasses after surgery.
LASIK is not possible without health risks-
It is a surgical procedure and therefore carries inherent risks that range from major to minor and include:
Some of the problems that could develop due to the procedure include irregular healing of the flap, perforation of the cornea, mild infection or keratoconus (degenerative corneal disease) that could distort vision but this again varies from patient to patient.
LASIK induced dry eye syndrome is the most common drawback which can make daily activities like reading, working, riding etc. physically miserable. This painful suffering can be diminished using prescribed eye drops like Restasis.
Visual aberrations might occur after the surgery which include halos and glare under dim lighting conditions, impaired night vision, fluctuations in vision sharpness and chronic eye pain and irritation that severely interfere with normal activities.
Awareness in candidates undergoing LASIK eye surgery-
It cannot provide perfect vision but can improve it and reduce the need for eye wear. It is not a fail-safe procedure and may require re-treatment to achieve optimal outcome. Candidates must be screened for the surgery through a comprehensive eye examination to ensure that they are ideal to undergo laser eye treatment.
Qualified ophthalmologists for surgery-
One should inquire about the experience and popularity of eye surgeons in the field of LASIK before opting for the refractive eye surgery. Don’t be afraid to search around on google for the very best local surgeons. Good doctors are those that properly diagnose the patient with thorough eye assessment for any eye diseases, provide details of the procedure and offer the highest standards of vision care.
