Based on these findings, the researchers elucidate that “mask wear changed the axis of astigmatism by an amount (>10° and >15°) which could impact toric IOL axis placement, overall toric IOL effect and refractive surgery targets.” Because of this possibility, the researchers warn that error...
trouble with night vision, and irritated eyes. The lens of the eye that is affected is behind the iris (the colored area of the eye). This lens filters light through the eye into the retina, allowing signals of the images that we see to transmit to the brain. ...
Corneo-scleral lenses often are a good choice for people who require larger-than-normal GP lenses for greater comfort. They also are frequently used when contact lenses are needed after LASIK or other corneal refractive surgery to correct irregular astigmatism. The size of lens used often is dete...
The “new” hard contact lenses are rigid gas-permeable (RGP) contacts. Made from a sturdy plastic material (often silicone) with a rigid design, you'd think these lenses were uncomfortable. However,it usually only hurts to wear them at first or if you get debris in your lenses. Are har...
aFor product registration of Oculus Boston XO (hexafocon A) Daily Wear Gas Permeable Contact Lens in China, State Food and Drug Administration (SFDA) had reverted with the following concerns recently XO lenses can be used for the correction of astigmatism and presbyobia. Not only so, SFDA wa...
If a person with this condition (calledanisometropia) cannot wear contact lenses safely or successfully, LASIK surgery might be the best way to fully correct their dissimilar refractive errors to prevent lazy eye. If you've been told you are at risk of amblyopia if you don't wear your glass...
