An Ideas Overview On Easy Plans In Keratoconus

LASIK is a two-step procedure to improve natural vision and reduce dependence on glasses and contacts. no dataThe outside layer of the eye, the cornea, is reshaped to focus light rays on the retina to send images to the brain. The first step involves a femtosecond laser to create a flap in the cornea, and the second step uses an excimer laser to sculpt the cornea to its desired shape. The flap is replaced over the treated area to aid in healing and comfort. In less than a few minutes, patients are taken from a lifelong handicap of poor unaided vision, to improved ability to see with reduced dependence on glasses and contacts. For many this may be the first time in their lives they have seen the world around them clearly. What advancements have been made throughout the 25 years of LASIK? Local eye surgeon, Jamie M Monroe, MD tells us, “as with most things, experience and technology have brought about advancements to improve results over time. When the FDA approved the treatment of nearsightedness 25 years ago, an average correction took the laser about two to three minutes to reshape the cornea. Over the years, changes have been made to improve accuracy and reduce the time and energy used for the treatment. In addition to nearsightedness, LASIK also is approved to treat farsightedness and astigmatism.” Custom wavefront guided treatments, using technology derived from the Hubble telescope in space, enabled surgeons to treat optical errors on the surface of the eye, and internal aberrations that were previously uncorrectable.

In more pronounced instances, corrective lenses or surgery can be prescribed. Other possible severe LASIK surgery side effects include permanent vision loss and under or overcorrection of the vision error. Partial-thickness cornea transplants are used to replace one part of the cornea. Being sturdier than soft lenses, GP contact lenses are easier to clean and last longer. You can also wear them while sleeping. Your family might be able to receive medical care through Maryland Medicaid.
