Refractive Cataract Surgery - Its Risks and Benefits

Refractive Cataract Surgery - Its Risks and Benefits Ophthalmology has realized the betterment of its field as it was honed and the knowledge over this field was improved over the constraints and development that it has undergone in refractive cataract surgery. It is said that with the current innovation and the latest generation of ophthalmology, it had reached to the point where "cataract surgery is refractive surgery". This means that from the previous cases of letting the patients wear glasses on regular basis after cataract surgery, now, there are premium lenses already which will not refuse the right of the patients to have the opportunity of achieving good uncorrected distance and near vision exist evidently.

Thus, from then on, what the personnel or enthusiast were lacking was the necessary time to deal with those patients and insufficiency in skill sets of the surgeon and ophthalmologists who experienced significant rational instability and inconsistency in outcomes. However, those were given solution and now, technology has paved the way to greater innovation in achieving visual acuity which complements with emmetropia.

At the end of any surgical operations, they have set a standard goal of correcting various problems regarding the prevalent eye irregularities such as nearsightedness, farsightedness and astigmatism. It had been a greater help because it is not possible to reduce the magnitude of higher-order optical distortion such as spherical aberration. Also, intervention to presbyopia introduces the newly developed intra ocular lenses which can correct the said condition.

In this way, refractive surgery is divided into two basic types of corrective surgery.

The first one is by changing the curvature of the cornea and the second type is by changing the internal optics of the eye by either replacing the natural lens of the eye or by using an intra ocular lens and attaching it to the natural lens. Through radial keratomy, incisions are made to various part of the cornea to correct nearsightedness and astigmatism. In the outer part of the cornea, it is incised to flatten the cornea in order to correct a mild to moderate degree of nearsightedness. With astigmatic keratomy, circumferential incision is made in the outer part of the cornea.

There are other options in refractive surgery which includes the following: Photorefractive Keratomy (PRK), Laser in-situ epithelial keratomileusis (LASEK), Laser in-situ keratomileusis (LASIK), Refractive replacement, and Phakic intraocular lens implantation. As with any type of surgery, we must be open that compilations can occur. The patient can experience complications such as flaring ones eye with lights at night, this may occur most of the time to those young patients who have large pupils; under correction or over correct is probable and may need for a second "enhancement" procedure; glasses may be required even after this surgery, and rarely corneal abnormality may need to use contact lenses; and in LASIK surgery, complications in the cutting of the corneal flap can lead to corneal irregularity.
