Refractive Surgery Eliminates Glasses for Many Astigmatic Patients

Thanks to continued advances in laser eye surgery, refractive surgery tools and techniques, glasses and contact lenses are fast becoming obsolete for many patients with astigmatism. Patients with undetected astigmatism often experience headaches, fatigue, eyestrain and blurred vision at all distances. Because astigmatism may not be recognized as the cause of these symptoms, this condition may go undiagnosed and continue to affect sufferers. Astigmatism can also be present in children, affecting their ability to see well in school and while playing sports.

Characterized by an irregular curvature of the cornea, astigmatism can be detected by regular eye examinations and successfully treated using procedures such as laser in-situ keratomileusis (LASIK), photorefractive keratectomy (PRK), laser epithelial keratomileusis (LASEK), laser thermokeratoplasy (LTK) and astigmatic keratotomy (AK; Table 1). An ophthalmologist can determine which type of procedure will work best for each patient.

Worldwide, >17 million people have undergone laser refractive surgery, and refractive surgery is one of the most commonly performed operations in the United States and by Beverly Hills LASIK surgeons. The newest laser-assisted procedures are approved by the U.S. Food and Drug Administration to treat up to 6 diopters (D) of astigmatism correction, which includes roughly 98% of all astigmatism patients. Advances in laser technology continue to improve treatment outcomes.

Guttman reported on a recent study by Barraquer, a private practitioner in Colombia, of 364 astigmatic myopic patients treated with a new generation “flying spot” excimer laser. Barraquer reported postoperative best-corrected visual acuity of 20/20 or better in 99% of treated eyes at 3 months. Astigmatic correction was achieved to within ±0.50 D in 92% of eyes.

Remember that for patients in or around Beverly Hills LASIK was used after the detection of astigmatism to treat it in its early and advanced stages. Because children may also have astigmatism, it is important that eye examinations be scheduled at regular intervals to detect any astigmatism early on.

Andrew I. Caster, M.D. has performed over fourteen thousand procedures to correct nearsightedness, farsightedness, and astigmatism. Dr. Caster is widely considered one of the most knowledgeable Lasik surgeons in the United States. Los Angeles Magazine selected Dr. caster as “The Best Lasik Surgeon in Los Angeles” and W Magazine listed him as one of two top Lasik surgeons in the United States.

Eyes Vision Surgery

Our eyes are one of our most precious resources and taking care of them is vitally important as they have to serve us right from birth all through our earthly stay.  Knowledge about eyes vision will help us gain a better understanding of the eye problems that occur and the corrective surgery that is available today, thanks to the enormous strides medical science has made.  Read all about the various problems and solutions in this article.

Astigmatism is an optical defect whereby your vision is blurry because of the inability of the eye to bring an object into sharply focused image on the retina; irregular curvature of the cornea or lens causes this eyes vision problem.  Astigmatic Keratotomy is a procedure that is performed to reduce the extent of astigmatism by reshaping your cornea from its original oval shape into a spherical shape. Anyone with a minimal or moderate degree of astigmatism who has had a stable prescription for a year at least and who does not have any serious vision problems can undergo this procedure to do away with the need for contacts or glasses.

INTACS is a procedure that is performed to reduce myopia and is an alternative to laser surgery. Tiny prescription inserts of plastic polymer are implanted in the outer edge of the cornea through surgery and they work by flattening the cornea to produce better focus and sharper vision.  The advantages to this type of procedure are that the inserts can be removed; flexibility to make prescription changes when needed; no tissue removal and zero maintenance costs.

Lasik eye surgery has become over the years the most popular refractive laser surgery to correct eyes vision.   A laser is used to change the cornea’s shape to correct the refractive error and the advantage to this system of correcting nearsightedness or farsightedness, even astigmatism is a permanent procedure.

Use the information contained in this article to better understand and correct your eyes vision problems successfully.
