I am 35 yrs, having -10 number & using lenses from last 14 years . My doctor have suggested me to have a lasik eye surgery if lasik eye surgery is safe for eyes?

The answer from Glenn is pretty good. Although I disagree on the nature of regression. Regression can occur with any prescription, a large residual prescription from large prescriptions are normally down to rubbish lasers (I saw this regularly with the VISX which has an amazingly good marketing pedigree for a machine that shouldn't even ablate pieces of innate plastic!). 220um of tissue for a -10D correction even with enhancements - rubbish laser... Stick to clinics that use the best lasers - the Wavelight Allegretto or B&L units provide an exponentially better laser profile and energy consistency. I don't see regression due to prescription size - age yes.If you do one thing when it comes to having treatment, make sure you have enough corneal tissue after correction : 250um may be the ''industry norm'' but 300um is considered much safer. What many clinics do in order to save tissue is reduce the optic zone of treatment from the usual 6.5mm to 6.0 or even 5.5mm. If you have large pupils, this will cause an increase in higher order aberrations. Do keep one thing in mind - the size of your prescription is immaterial. People with prescriptions of -1.00 or -12.00 are equally treatable and face the same risks. You do however need to be a suitable candidate first.Visit: www.lasik-eyes.co.uk for further information.

Lasik is safe and effective, but you have some circumstances that make you a less than ideal candidate.I work with a nonprofit Lasik patient advocacy. We don’t provide Lasik, just objective Lasik information and we certify Lasik doctors’ patient outcomes.Lasik reduces the need for glasses or contact lenses by reshaping the cornea (clear front of the eye). This reshaping is accomplished by removing tissue to make the center of the cornea flatter. Each diopter of refractive error requires about 12-18 microns of corneal tissue removed. At 10 diopters, you would need between 120 and 180 microns of tissue removed, but that is not all.Regression of effect is very common for people who have more than about 6-8 diopters of myopia (nearsighted, shortsighted) vision. Regression can often be accommodated by second enhancement surgery, but that means more tissue removal. It would be reasonable to expect as much as 220 microns of tissue removed to accomplish full correction.To remain stable, the cornea must have at least 250 microns of tissue untouched, and many doctors feel that not more than 50% of the cornea should be disrupted in any case. With these numbers, you would need to have a cornea at least 490 microns thick to maintain stability, but that is not all.The first step of the Lasik process is to create a flap of corneal tissue. This flap is about 100-120 microns thick. So adding the 250 minimum untouched, the upwards of 220 microns removed for initial and enhancement surgery, plus the 120 microns for the Lasik flap, and you now need a cornea that is at least 610 microns thick, and that leaves no room for error. The average cornea is about 500 microns (plus or minus) thick.Additionally, high myopia like yours is commonly caused because the eye globe is longer than normal. Unfortunately, the retina (thin membrane attached to the inside back of the eye that translates light into nerve impulses) is not normally larger to accommodate the longer myopic eye. That means there is a lot of stress on the retina to detach from the back of the eye. The additional trauma of Lasik may be a bit much for your retinas. If you decide to go ahead with any elective eye surgery, get your retinas checked by a retina specialist first.You may want to read more in a Lasik bulletin board thread at: http://www.usaeyes.org/ask-lasik-expert/viewtopic.php? t=1879The bottom line is that while Lasik may be safe and effective for most, you are not like most Lasik patients. Your individual circumstances indicate a higher probability of multiple surgeries and concerns about the stability of your corneas and health of your retina. You need a comprehensive examination from a competent surgeon to evaluate you carefully before you jump into Lasik.Glenn HageleCouncil for Refractive Surgery Quality AssuranceUSAEyes

PLEASE DONT DESTROY YOUR LIFE.I BEG YOU FOR GOD. http://lasikdisaster.com/ http://www.lasikcomplications.com/FOR MY OWN EXPERIENCE, DON'T DO ITAND PRIOR INFORMEDI AM VERY BAD... http://www.youtube.com/watch? v=3Lk_xD_0w…PD: THE DRY EYE IS FOREVER...

If you go for a free consultation, they'll explain all. I'm sure they'll alleviate any stresses you've got about the procedure.If I could afford it, I would definitely have it done.
Bette
its actually very safe if you have a good doctor and can make it so you dont have to wear lenses anymore
