Cataract and Astigmatism Correction

There are several methods modern-day cataract surgery can correct astigmatism. One alternative is to change the eye’s over cast natural lens with a special sort of costs intraocular lens (IOL) called a toric IOL.

A toric IOL works just like toric get in touch with lenses for astigmatism. That is, it has various powers in different meridians of the lens to deal with the unequal amount of nearsightedness or farsightedness in various parts of the eye that is particular of astigmatism.

There is a benefit of using a toric IOL to remedy astigmatism when a cataract is removed: Because the IOL is located firmly inside the eye, it can supply an extra secure adjustment of astigmatism compared to a toric contact lens, which moves on the surface of the eye with each blink.

For the greatest accuracy in the placement of a toric IOL, many cataract surgeons recommend laser cataract surgery. Because of the greater cost of a toric IOL and the included cost of using sophisticated laser innovation, the cost of cataract surgery that consists of astigmatism adjustment normally will be more than that of a basic cataract surgery.

Another way to deal with astigmatism during cataract surgery is called limbal relaxing cuts (LRI). In this procedure, several arc-shaped lacerations are made near the perimeter of the cornea. This carefully reshapes the cornea right into an extra spherical form, eliminating astigmatism.

If astigmatism is still a trouble after cataract surgery, added surgical procedures could be performed to minimize or eliminate it after your eye has completely recouped from your cataract procedure. These consist of: astigmatic keratotomy (AK), which is an LRI-like procedure executed with a medical blade or a femtosecond laser, and also LASIK.
