LASIK Laser Eye Surgery Blog at Eye Surgery USAThursday, July 31, 2008How is presby LASIK performed?With presby LASIK, laser energy reshapes your eye's clear surface into different zones. The laser light is bent or refracted differently in each zone so that both near and distance vision can be achieved simultaneously. Since presby LASIK is still in its investigational phases, different approaches are being studied to figure out how the eye should be shaped to attain the best possible vision correction for presbyopes. read more Labels: presby LASIK
Wednesday, July 30, 2008What Are The Benefits of Wavefront-Guided Custom LASIK?Many of the concerns surrounding LASIK are the post LASIK complications that may occur, such as glare, halos and difficulty seeing at night, which is why Wavefront technology is cutting-edge. It not only has the potential to improve your vision based on the standard 20/20 chart, but has the potential to improve the fine details and better contrast. Lower-order aberrations or small defects such as myopia, hyperopia and astigmatism can determine how much you can see. These defects can be treated with traditional LASIK. Higher-order aberrations or a measure of visual distortions more severe than normal vision problems that cause decreased vision at night, glare, shadows and halos cannot be treated with traditional LASIK and are sometimes a side effect of traditional LASIK. Thus the amount of higher-order aberrations determines how well you see. Wavefront LASIK can address these higher-order aberrations. Wavefront LASIK has the advantage of offering a higher quality of vision and not just a measure of how much you can see. On top of being able to achieve 20/20 or better vision, there is a reduced chance of losing visual quality such as contrast sensitivity, vision at night and distorted vision effects such as halos and glares. Wavefront LASIK is also ideal for those who have had vision correction procedures done already and have since lost the corrected vision, from previous LASIK, PRK and RK procedures.

Tuesday, July 29, 2008What is an excimer laser and how does it work?The excimer laser produces a high-energy, cold, ultraviolet light beam in pulses and delivers the pulses to a surface of the eye's cornea. These pulses break the bond between molecules and tissue cells so that a controlled amount of tissue can literally be vaporized away to reshape the cornea -- one microscopic layer at a time. The excimer laser is computer controlled and programmed to custom treat each individual eye with a high degree of precision. For most cases, the thickness of the layer removed by the laser is less than the thickness of a human hair. Labels: Excimer Laser

Friday, July 25, 2008Eye Anatomy and Refractive ErrorsRecent advances in refractive surgery are designed to permanently reduce or eliminate the need for corrective eyewear to see objects clearly. Today, more than 3 million corneal refractive procedures are performed worldwide each year. Presently, more than 100 million patients wear contact lenses for correction of their refractive errors. To better understand refractive surgeries, one should understand how a perfectly normal eye (20/20) focuses light and what are different types of refractive errors? Let us first understand the main components of eye. read more Labels: Eye Anatomy, Refractive Errors
Thursday, July 24, 2008Definition of a CataractA cataract is a clouding of the normally clear lens of the eye. A cataract decreases the amount of light that is focused on the retina, resulting in an overall blurriness of images. Having a cataract disturbs vision much like looking through a fogged windshield. The lens is the part of the eye that helps focus light on the retina. The retina is the eye's light-sensitive layer that sends visual signals to the brain. In a normal eye, light passes through the lens and gets focused on the retina. To help produce a sharp image, the lens must remain clear.The lens is made up of mostly water and protein. The protein is arranged to let light pass through and focus on the retina. Sometimes some of the protein clumps together. This can start to cloud small areas of the lens, blocking some light from reaching the retina and interfering with vision. A cataract can occur in any part of the lens: In the front, center, or the back part. The front cataract causes problem in vision as well as causes glare from the light. Central cataract causes problem in far vision and may not affect reading. Posterior cataract causes problem in reading. A combination of all the 3 forms may also occur. Labels: cataracts

Tuesday, July 22, 2008Familiar Vision ProblemsOver half the population of the United States experiences one or more common visual acuity problems. Generally, people with visual acuity problems are nearsighted, farsighted, and/or have astigmatism. Collectively, these conditions are medically referred to as lower order aberrations. Lower order aberrations are usually corrected by wearing glasses, contact lenses or by laser vision correction. Learn More Labels: vision problems
Monday, July 21, 2008When is LASIK not for me?You are probably NOT a good candidate for refractive surgery if: - You are not a risk taker. Certain complications are unavoidable in a percentage of patients, and there are no long-term data available for current procedures. - It will jeopardize your career. Some jobs prohibit certain refractive procedures. Be sure to check with your employer/professional society/military service before undergoing any procedure. - Cost is an issue. Most medical insurance will not pay for refractive surgery. Although the cost is coming down, it is still significant. read more Labels: LASIK
Friday, July 18, 200895% Satisfaction Rate with LASIKAccording to a global study conducted by the international body of scientific literature and reported by the American Society of Cataract and Refractive Surgery (ASCRS) more than 95% of LASIK patients are satisfied with vision. LASIK has been performed on over 16.3 million patients worldwide, backed up by more than a decade of clinical study and progressive technological advances, LASIK ranks among the most successful elective procedures today. "We find that there is solid evidence in the world's scientific literature to affirm that there is an exceptionally high level of satisfaction in patients who have had LASIK surgery," said Richard Lindstrom, M.D., president of ASCRS. Key findings from the study include:

Thursday, July 17, 2008Wavefront LASIKWavefront LASIK reshapes the cornea by using three-dimensional measurements of how your eye processes images to guide the laser. This provides a precise and individualized vision experience that would be otherwise impossible to achieve with traditional LASIK. The advantage of Wavefront LASIK is that it offers a higher quality of vision and not just a measure of how much you can see. On top of being able to achieve 20/20 or better vision, there is a reduced chance of losing visual quality such as contrast sensitivity, vision at night and distorted vision effects such as halos and glares.

Monday, July 14, 2008Female LASIK Surgeon, Dr. Elizabeth Miller, Provides FAQs on LASIKWhat Is LASIK? LASIK is a minimally invasive surgical procedure that reduces and in most cases eliminates the dependency on vision assisted appliances such as glasses and contact lenses. LASIK is an acronym for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A knife, called a microkeratome, is used to cut a flap in the cornea. The flap is folded back revealing the stroma or the middle section of the cornea. Pulses from a computer-controlled laser cut a portion of the stroma and the flap of the cornea is replaced. There are other techniques related to LASIK, some that do not involve cutting.

Friday, July 11, 2008Why do I need an eye exam?A complete eye exam is more than just updating your prescription for glasses or contacts. Your eye examination by an ophthalmologist consists of a series of tests to assess the overall health of your eyes. Your doctor also checks for eye conditions such as glaucoma, cataract, diabetes, hypertension, retinal detachments, etc. Labels: eye exam

Tuesday, July 8, 2008Advantages and Disadvantages of Conventional LASIKAdvantages Conventional LASIK can correct a wide range of simple prescriptions. It is less expensive than other types of LASIK, especially if it is performed on certain types of lasers which have a limited FDA-approved treatment range. Unfortunately, these lasers may not be able to enhance, touch up, or fine tune a less than optimal result. Disadvantages While conventional LASIK corrects simple prescriptions, it induces complex prescriptions (spherical aberration, coma, trefoil, etc.). These are unique imperfections in the cornea which can reduce visual sharpness postoperatively. Although 20/40 is the baseline expectation, even when 20/20 vision is attained, the quality of vision may not be satisfactory. Halos, glare, or night vision problems could result. Both the microkeratome flap creation and conventional laser treatment have been found to cause these unique imperfections and there is no way to predict who may experience symptoms or how severe they may be.

Monday, July 7, 2008How is Conductive Keratoplasty Performed?Conductive Keratoplasty uses radio waves, instead of a laser or scalpel, to reshape the cornea and bring near vision back into focus. CK is performed using a small probe, thinner than a strand of human hair, that releases radio waves. The probe is applied in a circular pattern on the outer cornea to shrink small areas of collagen. This circular shrinkage pattern creates a constrictive band (like the tightening of a belt), increasing overall curvature of the cornea. The procedure, which takes less than three minutes, is done in-office with only topical anesthesia (eye drops). Information provided by Boston Eye Surgeon, Dr. Ernest W. Kornmehl Labels: Boston Laser Eye Surgeon, Conductive Keratoplasty
Thursday, July 3, 2008What kind of vision can I expect the day after surgery?This will depend upon the type of procedure that you choose. With LASIK, many patients notice improved vision immediately after the procedure. Most patients are functional without their corrective lenses at the one day post operative exam. Patients continue to see a gradual increase in their visual acuity during the first five to seven days after the procedure. Labels: LASIK
