Types of Corrective Eye Surgery | Ophthalmic Surgeries

Contacts and glasses can make life difficult for some people. Many people are taking control of their vision and making it permanent.

In recent years, vision correction surgery has seen incredible improvements by eye specialists. Also known as refractive or laser eye surgery. There are many kinds of vision correction surgeries. The majority of procedures aim to shape the cornea to allow light to focus on the retina. Other procedures replace the lens.

Ophthalmic Surgeries

These are the types of corrective surgery, how they work, and what improvements they make.

LASIK (laser-in-situ Keratomileusis)

The procedure involves reshaping the corneal tissue to direct light into the eye and reach retina. This procedure is suitable for patients with astigmatism, nearsightedness, and farsightedness. The uniqueness of LASIK is in its method. To access the underlying tissue, eye surgeons make a flap from the cornea’s outer layer. This procedure is precise and computer imaging technology has allowed LASIK specialists the ability to create detailed images of the cornea and guide treatment.

PRK (photorefractive Keratectomy)

PRK uses a laser to shape the cornea. PRK is not like LASIK. It only reshapes your cornea’s surface. This procedure is ideal for people with mild to moderate nearsightedness, astigmatism, and farsightedness. PRK is also compatible with computer imaging technology.

LASEK (laser epithelial Keratomileusis)

This is a slightly modified PRK procedure. A doctor will make a flap to allow epithelial cells to be loosened using an alcohol solution. After the cornea is reshaped by the laser, the flap is secured with a soft lens to allow it to heal. LASEK is used to treat nearsightedness, astigmatism, and farsightedness.

ALK (automated laser keratoplasty)

ALK can be used to correct severe nearsightedness or very limited farsightedness. However, LASIK has almost completely replaced ALK as a method for correction. An eye specialist creates a flap on the cornea to reach the underlying tissue. To correct vision, the doctor uses a sub-layer of cornea instead.

RLE (refractive lens exchange)

RLE is a method to correct cataracts. A small incision is made to remove the natural eye lens from the cornea. The doctor replaces the lens with a silicone lens or plastic one. This procedure, also called CLE (clear lenses extraction) or RLR [refractive lens replacement], can be used for severe nearsightedness or farsightedness. This procedure can also be used to correct dry eyes and thin corneas. To correct astigmatism, additional procedures may be required.

EpiLasik

The EpiLasik procedure works in a similar way to PRK. The doctor removes a thin corneal layer and then shapes it. The doctor may remove or replace the layer. The doctor will then apply a soft contact lens that protects the area while it heals fully.

PRELEX (presbyopic lenses exchange)

Presbyopia is when the eye’s lenses lose their flexibility. Presbyopia patients have trouble focusing on objects close to them. PRELEX is when an eye doctor inserts a multifocal lens in order to increase flexibility and restore focus.

Intacs

Intacs can also be called intracorneal rings segments (ICR). The doctor will make a small incision on the cornea for this procedure. To flatten the cornea, two plastic rings in crescent shapes are placed on the cornea’s outer edge. This flat cornea allows light rays to focus differently on the retina because it is easier to adjust the angle at which they are focused. Laser-based treatments have replaced ICR for mild nearsightedness.

Phakic Intraocular Lens Implants

Phakic Intraocular lens Implants are necessary for patients who are too farsighted to have LASIK or PRK. The doctor makes a small incision on the cornea to insert the implant. It attaches to the pupil’s iris behind the pupil. The natural lens of the eye is kept in place.

AK (astigmatic keratonomy)

AK is a procedure that corrects astigmatism without using a laser. Astigmatic people have corneas that look like a football. This surgery corrects this by incisions made at the highest point of the cornea. The cornea will become more round after the incisions have been made. AK can be done alone or in conjunction with other laser eye surgery.
