If eyes were made of marble, we could correct every one of them to a perfect 20/20. But eyes are made of living tissue. As can be expected, not all eyes display the same healing response. The individual healing response, which cannot be predicted accurately, affects the patient’s final vision. Unfortunately, your eye’s healing response cannot be predicted by how fast other parts of your body heal and cannot be determined by testing.

In LASIK, there is much less variation in the healing pattern of the eye. The healing pattern varies more when the surface of the eye is healing, as in PRK, than when the deeper tissue is healing, as in LASIK.

Most people exhibit a predictable healing pattern. As the eye heals during the first several weeks or months, there is a slight tendency for the eye to revert toward its initial state: nearsighted eyes will regress very mildly back toward nearsightedness and far-sighted eyes will regress slightly back toward farsightedness. Doctors take this tendency into account, and will create a small overcorrection initially. As a result, most patients will notice that their vision sharpens during the first several weeks or months of the healing period.

As a patient you must decide: Do you want both eyes treated on the same day, or each eye on a different day? Each approach has advantages and disadvantages. Your decision may also depend on whether you are having PRK or LASIK.

When one eye is treated at a time, you can resume normal activities within a few days, because you can see well out of the untreated eye while the treated eye is healing.

Ethan had his eyes treated on different days. After the first PRK procedure, his vision was so blurry that he could barely see out of the treated eye. While it was healing, he wore a contact lens in the untreated eye. He could drive, read, and go to work. “I would just concentrate on seeing out of the one eye,” he said. “It’s difficult, but you can do it.”

Nicole, a thirty-seven-year-old actress, also had PRK performed on her eyes on separate occasions. After her first surgery, her eye was tearing and scratchy. “It felt like someone had kicked a whole pile of sand into my eyeball,” she said. She relied on painkillers to dull the discomfort and slept a lot during the next two days.

What are the odds of eliminating my need for distance glasses with excimer laser treatment?

Overall, 75 percent of patients will have perfect (20/20) vision without glasses, and 95 percent of patients will see well enough without glasses to pass the driver’s license eye test (20/40). The results are better than this for patients with low amounts of correction and often can be improved by retreatment when needed.

Does excimer laser surgery hurt?

There is only mild discomfort during the procedure, usually less than having your teeth cleaned. For the first few days after LASIK, there is usually a mild scratchy sensation. PRK patients will experience a little longer and greater discomfort than LASIK patients.

If you think surgical correction of nearsightedness, farsightedness, and/or astigmatism may be for you, the most important choice you will make is the doctor, even more important than deciding whether or not to have the procedure. A conscientious surgeon will help you decide whether excimer laser treatment is right for you by highlighting the pros and cons as they relate to your particular situation. The surgeon should discuss the advantages and disadvantages of PRK, LASIK and nonlaser procedures to help you choose which technique is best for you. The surgeon will also perform the procedure.

Eye floaters are unavoidable. Best ophthalmologists in the world say that you can’t prevent the formation of floaters in the eye, even if you consume anti-oxidant vitamins and good nutritional food. A healthy lifestyle is not even helpful in preventing formation of floater in the eye. But this problem is completely curable with Lasik laser treatment of eye floaters.

Floaters in the eyes is a problem in which a sufferer finds small spots, particles of dirt or threads which float gradually before his or her eyes. It makes a sufferer feel like a optical illusion or something coming from side of the eye. But these are not optical illusions. When these floaters change their place or fall in the source of the light and retina, then you due to the shadow of the floater a sufferer get some hazy image but for few seconds, which appears like optical illusion to the sufferer. This problem can be fixed with Lasik laser treatment.
