Different medical procedures supplant the focal point of the eye.

Here are the various sorts of restorative medical procedures, what they improve, and how they work.

LASIK (laser in-situ keratomileusis)

This surgery reshapes the fundamental corneal tissue to shine light into the eye and arrive at the retina. This method is great for patients who are myopic, farsighted, or have astigmatism.

PRK (photorefractive keratectomy)

PRK is a strategy that utilizes a laser to reshape the cornea. Not at all like LASIK, PRK just reshapes the outer layer of the cornea. It’s great for gentle to direct partial blindness, farsightedness, or astigmatism. PRK can likewise work with PC imaging innovation.

LASEK (laser epithelial keratomileusis)

This strategy is a slight variety of PRK. The specialist will make a fold where epithelial cells are relaxed by applying a liquor arrangement. Then, a laser reshapes the cornea and the fold is set and gotten with a delicate contact focal point so it can mend around the amendment. LASEK treats partial blindness, farsightedness, and astigmatism.

ALK (robotized lamellar keratoplasty)

ALK can assist individuals with serious partial blindness and barely any degrees of farsightedness, in spite of the fact that LASIK has everything except supplanted ALK as a technique for revision. For this strategy, an eye experts makes a fold in the cornea to get to the hidden tissue. No laser is utilized, and on second thought, the specialist makes an entry point in the sub-layer of the cornea to reshape and address vision.

RLE (refractive lens exchange).

RLE is a strategy for adjusting waterfalls. The specialist makes a little entry point to eliminate the normal focal point of the eye on the edge of the cornea. The focal point is supplanted with a silicone or plastic focal point. This system is otherwise called CLE (clear focal point extraction) or RLR (refractive focal point substitution) and can be utilized to address extreme farsightedness or partial blindness. It is additionally used to address dainty corneas, dry eyes, and other minor eye issues. Extra systems might be expected to address astigmatism. Read Also – Eyelid Surgery (Blepharoplasty Surgery)


The EpiLasik technique is basically the same as PRK. The specialist isolates a dainty layer of the cornea and afterward reshapes it. The layer may either be eliminated or supplanted. The specialist completes the methodology by applying a delicate contact focal point to safeguard the region until it can completely recuperate.

PRELEX (presbyopic focal point trade)

Assuming that the eye’s focal point loses its adaptability, the condition is alluded to as presbyopia. Patients with presbyopia experience issues zeroing in on close items. PRELEX is a system where the eye specialist embeds a multifocal focal point to further develop adaptability and reestablish center.


Intacs are otherwise called intracorneal ring portions (ICR). For this strategy, the specialist makes a little entry point in the cornea. Two sickle molded plastic rings are put at the external edge of the cornea to level it. The leveled cornea takes into consideration light beams to be changed in the manner they center around the retina. ICR has been supplanted by laser-based techniques to treat gentle myopia.

Phakic Intraocular Lens Implants

A few patients who are excessively myopic for PRK and LASIK, need Phakic Intraocular Lens Implants. For this method, the specialist embeds an embed through a tiny entry point at the edge of the cornea that connects to the iris behind the understudy. The eye’s regular focal point is left set up.

AK (astigmatic keratonomy)

AK is a surgery that remedies an astigmatism without the utilization of a laser. Individuals with astigmatism have corneas that are formed like a football, and this surgery revises that by making a couple of entry points at the steepest piece of the cornea. After the entry points are made, the cornea unwinds and takes a more adjusted shape. AK can be performed alone or with other laser eye medical procedures.
