Refractive Eye Surgery

Any surgery that is performed for the improvement of the refractive state of the eye is called refractive eye surgery. The common objective of all refractive eye surgeries is to eliminate the need of wearing corrective eye glasses or lenses on the part of the patient.

Some common visual disorders that can be cured with refractive eye surgery include myopia and astigmatism. Due to the high prevalence of such eye diseases, a very high number of refractive eye surgeries are regularly performed in the United States and other parts of the world.    

Methods of Refractive Eye Surgery
The process of this type of surgery involves remodeling the cornea of the eye. The most common technique in use these days involves an excimer lasers for reshaping of the curvature of the cornea. Some of the common methods of refractive eye surgery include:

* Flap Procedures: A blade called microkeratome is used in these surgeries to cut a flap of corneal tissue. Lasik or Laser Assisted In-Situ Keratomileusis is the most common example of this procedure which uses an excimer laser to target the desired tissue.

* Surface Procedures: Some common surgeries performed under this method include Photrefractive Keratectomy (PRK) and Laser Assisted Sub-Epithelium Keratomileusis (LASEK). These surgeries also involve the use of laser, however they do not require making a cut into the stroma of the eye.
* Corneal Incision Procedures: Radial Keratotomy (RK) is an example of surgery using this method. In this method a diamond knife is used for correcting the shape of the cornea. This surgery is used to common problems of eye such as myopia and astigmatism are cured. However, this method is mostly being replaced by methods which use an excimer laser.

Precautions and Risks in Refractive Eye Surgery
It’s true that refractive eye surgery is a modern and efficient method of correcting vision defects, however it is not suitable for every one. If you are a victim of common diseases such as diabetes or glaucoma then the refractive surgery would not be suitable for you. You should also avoid this type of surgery if you are a pregnant or have certain eye diseases involving retina or cornea defects.

A variety of eye tests

Many people can not realize that their vision is actually declining gradually that a pair of eyeglasses is needed or there should be a change of eyeglass prescription. It is highly recommended by most eye doctors that individuals should visit an eye doctor for regular eye tests. Actually an eye testing is more than offering prescription check or update. Comprehensive eye exams are also capable of detecting early signs of eye diseases such as glaucoma and cataracts. Other vision-related health problems such as diabetes and high blood pressure can also be monitored.

Eye test is just a basic concept and there are a variety of eye tests. Each one has its own feature and function, which in most cases can not be replaced with another. In this case, people who are planning to see an eye doctor for an eye exam should keep clear in mind the difference of the kinds of eye tests and what they can get from certain tests.

A focimetry exam is always conducted by the doctor to determine the current prescription strength if the patient is wearing eyeglasses. To ensure the stability of the prescription, the eye doctor is also likely to give refraction, which can also verify the current prescription. In detail, an auto-refraction will first be used to determine the baseline prescription. And a second light-based exam named slit lamp exam can examine the patient’s cornea, conjunctiva, lids, iris and lens using a microscope and a small beam.

For additional information, the patient can also receive an ocular muscle assessment, which can evaluate the strength and flexibility of the eye muscles. Moreover, a tonometry exam is sometimes carried out to measure the eye pressure, which always helps in diagnosing glaucoma. At the last, the internal eye may be tested through a retinal exam, in which case eye drops are needed.

Regular vision examination is only one of the services that are enabled by consulting a health professional for everything checks. These doctors’ visits are indispensable actions to maintain a healthy lifestyle, in addition to exercising, taking vitamins, eating healthily and refraining from smoking and so on.

Why do doctors perform LASIK as the most common vision correction procedure?

Many patients have asked a relatively simple question, “why was LASIK invented at all”? A decade ago very few people even knew the word LASIK, and while the word had become a part of our lexicon, the real reason that doctors choose to do LASIK escapes many peoples understanding. We were one of the first handful of doctors in the United States, and the first to realize the potential benefits of LASIK for vision correction almost fifteen years ago. Since that time there are now over 10,000 LASIK doctors in the USA alone and a multiple of this number worldwide. The reasons for the success of LASIK are numerous but in a sentence it provides rapid, accurate, and relatively painless restoration of vision to a wide range of refractive errors. Patients are able to see like they were wearing contact lenses without all of the bother, cost, inconvenience, and risks of contacts. In general they have better visual function than provided with glasses in the same way that contact lenses are better than glasses for so many reasons.

This simple question is profound, because it touches on an invention that has changed the way in which the world views vision correction and has helped millions of people worldwide to see better without the aid of glasses or contact lenses.

For perhaps millions of years, much of human kind has suffered with vision problems. There are the serious eye diseases such as cataracts, glaucoma and a myriad of other problems. Beyond this is the simple fact that many people are unable to see clearly at distance, near, or both. This is from the imperfections of the eyeball as a camera and this was greatly helped over that last few hundred years by glasses and more recently in the last 50 years by contact lenses. Although with the advent of lasers, there was a hope that such technology could improve vision, limitations in the nature of the eye had limited laser application to vision correction until the advent of LASIK .

LASIK is a hybrid procedure, that is it involves two steps which together are able to improve vision very rapidly and predictably for patients with ametropias. The first step is to create a potential space for the laser to correct the vision and the second is to do the correction itself. In the early days of LASIK about 15-20 years ago , this potential space was made with a device called a microkeratome. This is a miniature shaver which can peel a thin layer of outer tissue from the cornea which remains attached at the edge or “hinge”. Another laser, the excimer laser then focuses on the freshly cut surface, and removes tissue in a programmed manner to reshape the eye. Finally, the flap is replaced which assumes the contour of the newly shaped cornea beneath it. It is the transfer of the shape combined with covering the treated area with living tissue that makes LASIK so remarkable. Healing occurs at the edge or seam of the flap and the eye barely knows that anything has occurred beneath. The vision is rapidly restored with no significant healing response, which is key to the success of LASIK.

Newer lasers, called femtosecond lasers, are able to make the flap layer more precisely without a cutting blade but fundamentally perform the same function. This all laser approach is a safer and slightly more effective way of restoring vision by LASIK. The current state of the art in LASIK is to use advanced femtosecond lasers such as our Visumax to make a flap, and a wavefront optimized excimer laser like our Zeiss or our Allegretto laser(s) to reshape the cornea. With this type of treatment we have a very low complication rate, and excellent vision results in most cases.

We become complacent very quickly with new technologies but it is a truly amazing and revolutionary accomplishment that in a procedure that lasts only a few minutes , a persons vision can be corrected from a lifetime of limitations.

Dr. Dishler is the first doctor to perform LASIK in Colorado, the first doctor to offer blade free LASIK in Colorado, and is a consultant, lecturer, and inventor. He is involved with several FDA studies and answers questions related to laser vision correction online.
