For people who wear glasses and contact lenses to correct their vision, laser eye surgery is an increasingly attractive alternative. Laser eye surgery is used to treat nearsightedness (nearsightedness) or sometimes farsightedness (farsightedness). There are two main types of laser eye surgery: LASIK and LASEK. LASIK stands for laser in situ keratomileusis and LASEK stands for laser-assisted subepithelial keratomileusis. LASIK is a more widely used laser surgery method: LASEK is mainly applied when a person does not meet the health or age requirements required for a LASIK procedure.
Cornea and lens
In the human eye, the cornea and lens play an important role in directing light to the retina. When the cornea and lens cannot do this, the images will be blurry. We call the resulting blurriness refractive error. LASIK eye surgery uses a laser beam to correct abnormalities in the cornea and lens. The ophthalmologist evaluates each patient and determines the amount of corneal tissue that must be cut to correct her vision.
The LASIK procedure for each eye takes about 15 minutes
The surgeon first paints the eye with eye drops to relieve pain. A microkeratome is used to cut and make a thin flap from the cornea, which is then removed to expose the corneal tissue. The excimer laser is then used to reshape the cornea, after which the flap is carefully returned. No stitches required – the body’s natural healing processes are necessary to rebuild the eye.
After completing the LASIK procedure, you will need to wear an eye patch that acts as a physical barrier to the itchy sensation after surgery. The patch should not be removed until at least 8-10 hours after the operation.
Not everyone is eligible for LASIK eye surgery
Pregnant or nursing women should not have LASIK because their current eye measurements are not normal. In such cases, the LASIK procedure may seem effective right away, but it can actually damage the mother’s sight in the long run.
LASIK is also not recommended for people taking certain prescription medications, such as oral prednisone and Accutane. However, this can be done after you stop taking the medication (that is, if you are taking the medication temporarily). Those with conditions like diabetes and lupus, which can affect vision, should also avoid LASIK eye surgery. Age is also a determining factor: older people are recommended to undergo LASEK surgery. In general, the general health of the patient should be considered.
Although LASIK for Myopia is a viable alternative with a high probability of success, there are potential complications, although this is rare. Some of the complications include corneal infection; corneal deformity that makes contact lens wears difficult, dry eyes, photosensitivity, and itching. Before the procedure, the benefits and risks must be weighed. If you don’t mind wearing contact lenses or glasses, you can do without LASIK.
