Conductive keratoplasty for hyperopia correction

As a non-laser refractive surgery, conductive keratoplasty (CK) can be used to correct mild hyperopia. NearVision CK is now the widely applied CK surgery.

Wavefront LASIK for better refractive correction

Using 3-dimensional measurements of the way your eye processes images, wavefront LASIK provides some extremely precise correction results, which are beyond conventional LASIK, contact lenses and eyeglasses.

Special corneal devices for vision correction

As a potentially new form of refractive surgery, corneal inlays and onlays are special. Like LASIK and PRK, corneal inlays and onlays alter the way light rays enter the eye.

Post-surgery contact lenses for visual remedy

Although there is high success rate, refractive surgeries including LASIK are not perfect. Postoperative visual problems may affect overall correction outcomes.

Advantages of bladeless LASIK

While conventional LASIK uses mechanical cutting tools, all-laser LASIK performs in a different way. Also named bladeless LASIK, all-laser LASIK takes use of two types of lasers: femtosecond laser and excimer laser.

Advantageous implantable lenses

Also called phakic intraocular lenses, surgically implanted lenses are surgical alternative to LASIK and proved to create better vision results.

Advantages of wavefront LASIK

As optical irregularities, aberrations have two main types: lower order aberrations such as nearsightedness and astigmatism and higher order aberrations that can not be corrected by eyeglasses. Examples of higher order aberrations include spherical aberration and coma.

A variety of vision correction surgeries

Before the 1950s, there were only eyeglasses for refractive vision correction. Nowadays, there are still contacts lenses and other surgeries that are used to correct refractive errors.
