What can laser eye surgery correct?
Laser eye surgery could not only cure myopia, hyperopia and astigmatism, but also could be used in keratoconus therapy and corneal transplantation surgeries (such as optical corneal layers transplantation). Especially the gradually use of Femtosecond Laser technology in refractive surgery. Femtosecond Laser could make corneal flap more convenient and precise than traditional keratome(such as Moria 2). And less complications.

Differences between the cow eye and human eye?
I read a thread of what are the differences between the cow eye and human eye? I really get no ideas. We can think as follows: The one is human’s, the other is cow’s. The size of the eye is not the same. The cornea diameter of the cow eye is bigger than humans, and anterior chamber depth of it is deeper than humans, and lens is larger than us. But we should know, all creature’s optic system is not perfect. Perhaps myopia or hyperopia and astigmatism may happen in animals not just More >

Astigmatism treatment methods

Astigmatism treatment methods
How to make a success with refractive lens exchange? It depends on the patient’s education, expectation, surfacial status of the eye, such as tear film, fundus of the eye and the rate of posterior capsule opacification. The most important is to reduce residual refracive error, especially the astigmatism.
Treatment methods:
1. Spectcles. Wear toric glasses.
2. Toric contact lens. Such as soft contact lens and RGP.
3. Corneal surgery.
