Vision Correction Methods for Better Eyesight: What Are They?
People who use contact lenses or spectacles may choose eye correction surgery at some point. And if you have greater numbers on your eyes, wearing glasses or contact lenses might sometimes be agonizing and annoying over a length of time
There are numerous types of eye surgery available today. And each has its own set of perks. But eye doctors at Krishna Eye Centre, a leading eye clinic, can advise you on which is ideal for your eyes.
Let us go through the many sorts of corrective vision surgery in greater detail, but before that, let’s take a look at the types of vision errors these techniques can treat.
The 4 types of refractive errors
Nearsightedness
Nearsightedness is also referred to as myopia. This disorder is caused by an a longer eye ball , which causes light to focus before it reaches the retina at the rear of the eye. This makes it harder to perceive distant objects.
Presbyopia
Presbyopia is when it becomes difficult to read and see objects close to you clearly. It occurs as you age when your eye lose the capacity to adjust focus between distant and close things. It is normal for people to develop this presbyopia in their 40’s and it progresses upto 60 years of age.
Farsightedness
Farsightedness is also referred to as hyperopia. This disorder is caused by a shorter eye ball, which causes light to focus beyond the retina. This makes it difficult to perceive objects that are close to you.
Astigmatism
Astigmatism frequently creates distorted images and may induce symptoms like double or tilted vision. It usually occurs when the cornea of your eye is irregular rather than spherical in curvature, although there may be other causes.Sometimes Astigmatism can be caused by altered shape of crystalline lens and also the shape of eyeball itself
Types of eye surgery
LASIK (laser in-situ keratomileusis)
During this operation, the underlying corneal tissue is reshaped to focus light into the eye and reach the retina. Those who are nearsighted, farsighted, or have astigmatism will benefit from this surgery. In order to access the underlying tissue, eye surgeons make a flap of the cornea’s outer layer. Precision is required in LASIK eye surgery for farsightedness, and advances in computer imaging technology enable LASIK physicians to develop comprehensive corneal pictures and guide therapy.
PRK (photorefractive keratectomy)
PRK is a laser-assisted corneal reshaping treatment. Unlike LASIK, PRK merely reshapes the cornea’s surface. It is suitable for people with mild to severe nearsightedness, farsightedness, or astigmatism. PRK can also be used in conjunction with computer imaging technology.
RLE (refractive lens exchange)
RLE is a cataract surgery treatment. The doctor creates a small incision on the cornea’s border to remove the eye’s natural lens. A silicone or plastic lens is used in its stead. This surgery, also known as CLE or RLR (refractive lens replacement), can be performed to rectify extreme farsightedness or nearsightedness. It also treats thin corneas, dry eyes, and other minor vision issues. To correct astigmatism, additional surgeries may be required.
PRELEX (presbyopic lens exchange)
Presbyopia occurs when the lens of the eye loses flexibility. Presbyopia patients have difficulties focusing on close objects. PRELEX is a surgical treatment in which an eye specialist inserts a multifocal lens to improve flexibility and focus.
Intraocular Phakic Lens Implants
Phakic Intraocular Lens Implants are used in patients who are too nearsighted for PRK or LASIK. The doctor inserts an implant through a very small incision at the edge of the cornea that links to the iris behind the pupil for this surgery. The natural lens of the eye is left in situ.
