Refractive eye surgery is any eye procedure used to improve the refractive condition of the eye and eliminate or decrease dependency on contact lenses or glasses. This may consist of numerous methods of surgical remodeling of the cornea or cataract operation. The commonest methods at present use excimer lasers to reshape the cornea's curvature. Successful refractive eye procedures may reduce or cure popular vision conditions like astigmatism, myopia and hyperopia, and also degenerative conditions such as keratoconus.Techniques Flap procedures
Excimer laser ablation is performed under a partial-thickness lamellar corneal flap
- Automated lamellar keratoplasty
- Laser-assisted in situ Keratomileusis (LASIK)
- Refractive Lenticule Extraction (ReLEx):
The excimer laser is used to remove the most anterior part of the corneal stroma. These procedures don't need a partial-thickness cut into the stroma. Surface ablation procedures vary only in the way the epithelial layer is taken care of.
Corneal incision procedures
- Photorefractive keratectomy (PRK)
- Transepithelial photorefractive keratectomy (TransPRK)
- Laser Assisted Sub-Epithelium Keratomileusis (LASEK)
- Customized Transepithelial No-touch (C-TEN)
- Radial keratotomy (RK)
- Mini Asymmetric Radial Keratotomy (MARK)
- Arcuate keratotomy (AK)
- Limbal relaxing incisions (LRI)
- Radial Keratocoagulation
- Laser thermal keratoplasty (LTK)
- Intrastromal corneal ring segments (Intacs
- Phakic intraocular lens (PIOL)
- Generally refractive surgery
- Presbyopia correction
Ophthalmologists use many approaches to examine the results of refractive surgery and change their techniques to offer better results in the future. A few of these approaches are programmed into the devices ophthalmologists use to gauge the refraction of the eye along with the shape of the cornea, like corneal topography.Refractive surgery may be a wise idea for you if you:
- Want to reduce your reliance on contact lenses or glasses;
- Are free of eye illness;
- Accept the inherent dangers and possible side effects of the surgery;
- Understand that you may still require contacts or glasses after the surgery to achieve your best vision;
- Have a suitable refractive error.
There is no universally-accepted, most convenient way for correcting refractive problems. The best choice for you must be decided after an intensive discussion and evaluation with your ophthalmologist. If you are thinking about refractive surgery, you and your Eye M .D. may discuss your vision and lifestyle needs to figure out the best procedure for you.
Risks : People with particular eye ailments involving the retina or cornea, patients, and pregnant women, who have medical problems like autoimmune diseases, diabetes, glaucoma, or uncontrolled vascular disease, aren't good candidates for this surgery.
Keratoconus is a progressive thinning of the cornea, which is a usual corneal illness. Keratoconus taking place after refractive surgery is known as Corneal Ectasia. It's thought that extra thinning of the cornea via refractive surgery might lead to the advancement of the condition, which may result in the need for a corneal transplant.
Corneal pachymetry and topography are used to diagnose for abnormal corneas. In addition, the shape of some people's eye might not allow effective refractive surgery without taking out excessive quantities of corneal tissue. Those considering laser eye procedure must have a complete eye evaluation.
Though the risk of complications is reducing in comparison to the early days of refractive surgery, there's still a little chance for serious issues. These are vision issues like dry-eye syndrome, halos, ghosting, double vision, and starbursts. With procedures which make a lasting flap in the cornea (like LASIK), there is as well the chance of accidental traumatic flap displacement years after the procedure, with possibly devastating results if not offered prompt medical attention.
For patients with strabismus, risks of complications like diplopia and/or increased strabismus angle should be examined thoroughly. In the event both strabismus surgery and refractive surgery refractive are to be done, it’s suggested that the refractive surgery be performed first.
