PRK VS LASIK

lsi1 — Fri, 20 Feb 2009 06:57:35 +0000

Remarkably, there is a more rapid improvement in vision and decreased discomfort with LASIK since the surface epithelial cells have been preserved and do not need to grow again. This is indisputably the reason that LASIK has become the most preferable corrective surgery for both doctors and patients. However, in some patients, PRK is a safer alternative to LASIK that may promise better outcomes. Patients who might benefit from PRK include those with less corneal tissue or in some patients with corneal irregularities or scars.

MONOVISION LASIK

Monovision LASIK initially was used off label, as it had not received official FDA approval as a remedy to correct presbyopia. However, it received approval from FDA in July 2007. You Monovision lasik is a procedure that permanently corrects one eye for distance vision, while correcting the other eye for near vision. It is the most recent development in presbyopia treatment. Monovision lasik is most ideal for the patients who are mildly hyperopic.

LASIK PROBLEMS

There has been an increase in the number of older patients who demand for Lasik surgery. Since these patients represent special challenges, they are continuously exposed to lasik problems. Increased age has been previously associated with poorer final clarity of vision, as measured on an eye chart. The case histories of around 700 consecutive laser eye surgeries, performed to correct nearsightedness, farsightedness and astigmatism, reveal that there was 20/40 chances of visual acuteness for 91 to 100% of patients.

WAVEFRONT LASIK

Many patients nowadays do not realize that the eye is an imperfect optical system. As light rays pass through the individual optical components of the eye, they are subject to being twisted by the flaw found in the cornea and the crystalline lens. In order to achieve a normal corneal re-shaping, the higher order optical aberrations are measured with the help of Wavefront lasik system, as this technology can diagnose and measure aberrations that no other system can even see. It is important to understand that without a Wavefront Lasik diagnosis, it is impossible for a doctor to accurately determine which surgical method is worth considering for a patient.

ASTIGMATISM LASIK

Astigmatism caused by wound dehiscence after cataract extraction, can also be corrected through astigmatic keratotomy or LASIK. Astigmatism Lasik openings, unless extremely short or long, typically are neutral with respect to the spherical equivalent. Newer laser software is now able to correct hyperopic astigmatism by steepening the flat axis. Although an ideal goal of Astigmatism Lasik is to correct all of the astigmatism, a more realistic goal is to make the use of contact lenses or glasses comfortably

EPI LASIK

Many surgeons consider Epi Lasik as a better option for some patients who probably will not do very well with Lasik. These include people who have steep corneas, with not enough tissue for a good Lasik flap. Some people who continuously run the risk of being hit in the eye, such as police officers, army men, boxers and sportsmen are also a suitable candidate for Epi Lasik.

EYE CARE

Need for Eye Care: Eye Care is a significant factor in our day-to-day lives. They are the windows to our soul. We should not be taking eyesight for granted. People with serious eye problems are not able to see life experiences to a very large extent or sometimes not at all. This necessitates the need to know more about Eye Care, for both personal and financial reasons. Eye Care is very important for maintaining high health. People with eye problems find it very difficult to perform daily activities like cycling, reading and walking. This also leads to emotional stress, which can lead to isolation and depression. This strain in turn also affects social relationships. Treating eye problems can also be very costly for the patients..

LASER VISION CORRECTION

lsi1 — Wed, 18 Feb 2009 09:21:05 +0000

Laser vision correction is a most advanced procedure, wherein the curvature of the eye is reshaped in a matter of just a few minutes. This is done with the help of computer-controlled instruments and advanced excimer laser. Vision is improved by focusing light rays more directly on the retina to create a clearer image. The objective of laser vision correction is to improve your uncorrected vision and decrease the dependency on corrective lenses. Custom laser vision procedures treat both lower and higher order aberration to potentially achieve a higher quality of vision. Many people achieve 100% vision through laser vision surgery without glasses or contact lenses..

EYE SURGERY

Cosmetic eye surgeries are performed to maintain a youthful appearance. Repair of droopy eyelids, facial restoration procedures, eye lifts and even brow lifts are a part of cosmetic eye surgery. Eye surgery techniques have become so advanced that taking up a cosmetic eye surgery is no longer a tough decision for patients. These forms of appearance enhancing eye surgeries are attracting more and more people despite of the costs and risks involved.

CORRECTIVE EYE SURGERY

lsi1 — Sat, 14 Feb 2009 06:55:17 +0000

Clear vision depends on how well the cornea and lens allow light rays to fall onto the retina. Light rays must be bent to focus on the retina. The retina being light-sensitive, creates an inclination from the light rays that are sent through the optic nerve to the brain. If the shape of the cornea or eye is not normal, then vision becomes blurred as light does not fall properly on the retina. This is known as a refractive error. Such errors are usually corrected by corrective eye surgery commonly known as reflective eye surgery. Refractive errors can include myopia, hyperopia, astigmatism and presbyopia.
