Reason to Be Happy With Quick Weight Loss

A determination of the refractive error is the “dry” or undulated state. The second is a encyclopedic refraction. This is similar to a manifest refraction except it is completed while your eyes are dilated. The reason for the encyclopedic refraction is to insure that the manifest is correct. When The 10 Day Smoothie Cleanse Review your eyes are dilated, you are unable to accommodate (focus up close) during the test. Once your visual acuity has been determined, the results will be compared to your previous prescription to assure stability in refractive error. There should not be more than a half a dipterous change in the past two years.

The next eye examination is performed with an instrument known as a slit lamp microscope that allows a binocular, high magnification view of the eye. This examination is used to rule out the presence of disease. Radiometry is used to measure corneal curvature and is completed with a tetrameter. This measures the shape of your cornea. Many surgeons have sophisticated topography equipment that obtains these measurements.

An Ophthalmologist is used to examine the back of the eye or “retina” to exclude any tears, detachment or predisposing conditions. The optic nerve that carries vision from the retina to the brain is also observed for signs of glaucoma.During consideration of having SILAS - Laser Vision Correction, each patient must weigh the benefits and risks of having such a procedure. It is essential that patients understand potential risks associated with the SILAS procedure. Although, it has received FDA approval and is considered to be safe, there is risk of having a serious vision-threatening complication. While approximately 1% of patients have complications with their SILAS procedure, even fewer experience a serious flap related complication. 

SILAS is an extremely effective procedure that is suitable for high, moderate or low prescriptions.Complications can occur due to the Laser component of the procedure or the Mastectomy step of the procedure. There have been no reported cases of blindness following either PR or SILAS, anywhere around the world. Under correction, is when the intended amount of laser correction is not obtained during the primary procedure. In extreme cases of under correction, after stabilization, an enhancement may be necessary to obtain optimum results. Under correction can result from a number of factors: the healing response of the eye, the hydration of the cornea during treatment, the laser's calibration, or temperature and humidity. Often time under correction is deliberately induced to create a mono vision effect.
