PRK disadvantages include a longer recovery time for vision in contrast to LASIK which may be between five days and two weeks for blurred vision to properly clear. [4] [6] Another disadvantage is that patient may be required to apply steroid eye drops for a few weeks longer than that of a LASIK procedure. [3]
Those considering laser eye surgery should have a full eye examination. Although the risk of complications is decreasing compared to the early days of refractive surgery, [32] there is still a small chance for serious problems. These include vision problems such as ghosting, halos, starbursts, double-vision, and dry-eye syndrome. [33]
Cataracts and glaucoma both cause blurry vision. If the lens isn’t the right size, you may experience other visual issues such as glare or double vision. Endothelial cells in the cornea are reduced as a result of eye surgery and aging. If the cells die too quickly, a cloudy cornea and vision loss may result.
The femtosecond lenticule extraction (FLE then FLEx) procedure was first introduced at the American Academy of Ophthalmology Annual Meeting in 2006 by Walter Sekundo and Marcus Blum, and was first published in 2008 by Walter Sekundo et al. [7] [8] [9]
Post operative epithelial healing time is also more for PRK. [22] Laser assisted in situ keratomileusis (LASIK): Laser eye surgery to reshape the cornea, so that glasses or contact lenses are no longer needed. [20] [23] Excimer laser LASIK can correct hypermetropia up to +6 diopters. [21]
Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery , where the cloudy lens is removed to treat a cataract , clear lens extraction is done to surgically correct refractive errors such as ...
The procedure results in a decrease in nearsightedness. According to the PERK study, 58% of eyes were corrected within 1.00D of goal 3 years after surgery. Additionally, 76% of eyes had uncorrected vision of 20/40 or better at 3 years. [5] From 2 to 10 years post-operatively 43% of eyes had an increase in farsightedness by 1.00D or more.
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage.
