LASIK is an acronym for laser-assisted in-situ keratomileusis which is an eye surgery. Lasik surgery is the most well-liked method for correcting visualization difficulties caused by refractive error, in which the eyes fail to focus light appropriately. Lasik surgery treats nearsightedness, farsightedness, and astigmatism, radically decreasing and often abolishing the requirement of glasses or contact lenses.
This is the following process of Lasik surgery:
Initialy, the eye is anesthetized with use of limited anesthetic drops. Once you can't sense your eye, a small flap is formed on the surface of the cornea by means of a particular instrument known as a microkeratome which allows the surgeon to access the corneal bed.
After cautious placement of the corneal flap, a cool-beam, excimer laser restructures the cornea, shifting the eye's focal point to endow with clearer vision.
The corneal flap is then softly relocated and will begin to cure instantaneously.
In conventional Lasik surgery reforms the cornea, the part of the eye that visualizes light on the retina. In Lasik surgery, that reshaping ensues after a planned laser treatment taking into account the precise refractive error of the eye. A nearsightedness disease is corrected by flattening the cornea, while farsightedness is fixed by steepening the cornea. The concluding result of lasik eye surgery is for most patients, vision good enough that they no longer need glasses or contacts for most activities.
But in customized lasik surgery, physicians apply it to patients to reduce night vision turbulences like glare and halos. A good percentage of custom Lasik surgery recipients gain twenty by twenty visions from this method, which uses modified treatment in the form of the wavefront analyzer, which permits for a higher level of diagnostic information.
Wavefront technology begins through NASA, where it was initially used for high-powered telescopes. The wavefront analyzer generates a detailed map of your visual system twenty-five times more precise than standard lasik surgery can produce. This level of fact allows for tiny irregularities known as higher order aberrations to be incarcerated and fixed. This highly customized data which is then transferred to the laser used in your Custom lasik surgery treatment, where it will best treated for your sole vision problems.
Lasik surgery can fix up the vision of the nearsighted, the farsighted, and those with astigmatism. Once you have had your lasik surgery, you will possibly want to recommence your normal activities almost instantly, but be cautious. Whilst in lasik surgery, you should still pursue this rough timeline before you jump back into your normal activities.
A person wearing glasses or contacts will ask for refractive surgery because this simple procedure reshapes the corneal tissue and corrects any existing refractive errors.
Photorefractive keratectomy (PFK), Radial keratomy and Lasik vision surgery are all current procedures but the medical experts consider the latter as being the most affordable and fastest one.
After a Lasik vision surgery, 99% of the patients don’t need their glasses anymore while the same percent is used to determine the visual acuity. This type of surgery is a delicate mixture of laser treatment and surgical procedures.
At first the surgeon creates a flap and lifts it to one side so that he can use the laser to reshape the cornea.
There are a few risks involved here because the major optical function of the eye is altered by this refractive surgery.
That’s why it’s very important that your surgeon explains you all the risks and complications, the side effects and also the limitations of this procedure.
Lasik vision surgery won’t interfere with your eye’s aging process. If you choose to have this procedure because of occupational vision requirements then there’s a big chance that both you and your boss will be pleased with the results.
In order to be a good candidate for the surgery, the patient must be at least 18 years old and must have a normal corneal structure. Also, before the procedure the lenses are strictly forbidden (3 weeks for soft lenses and 4 weeks for hard ones).
The procedure is not performed on patients that suffer from any condition that can affect the corneal wound healing (immunosuppression, corticosteroid use, etc.) or on patients that have untreated superficial eye disease.
An improvement over PRK, Laser-assisted In Situ Keratomileusis removes a stromal layer by flattening the curvature of the cornea. Using a microkeratome, the doctor creates a corneal flap and retracts this tissue less than 1/3 of the thickness of a human hair in order to access the corneal stroma and use the excalculated measurements.
Next, he rolls back and repositions the corneal flap.
Lasik surgery provided great results in correcting residual myopia that usually appears after cataract surgery. It is safe (safer than PRK), stable and predictable, it causes less post-op discomfort and involves only a few minor side effects.
Not to mention that after the surgery, the patient has no corneal haze and there’s no need for complicated postoperative care. Even so, you should be aware that any complications are more severe than the ones with PRK because the laser works on a deeper level of the cornea.
After Lasik vision surgery, the DLK must be taken into consideration because this is a non-infectious, peculiar and inflammatory reaction in the lamellar interface.
To be more precise, for a multi-factorial cause in the first week after the surgery may occur a diffuse, white, culture-negative, granular lemellar keratitis.
