The human eye is constantly changing throughout life. When we are young, our eye has a negative spherical aberration. During middle age, this becomes a zero spherical aberration. Eventually, this becomes a positive spherical aberration. While this is normal for the eye as we age, implanting a traditional intraocular lens during cataract surgery may increase spherical aberration even further.

Traditional intraocular lenses are spherical, meaning the front surface is curved. Aspheric intraocular lenses, however, are slightly flatter in the periphery and are designed to provide better contrast sensitivity. Due to their shape, aspheric intraocular lenses are often good choices for implants for those who have pre-existing positive spherical aberration. Using the aspheric intraocular lenses instead of traditional intraocular lenses during cataract surgery may improve sight for these patients even further.

The aspheric intraocular lens is also a popular intraocular lenses choice because it corrects for many of the problems common with cataract surgery. Halos, glare, and reduced contrast are all common problems associated with cataract surgery and intraocular lens implantation, but can be avoided with the use of aspheric intraocular lenses.

Potential complications with the aspheric intraocular lens implantation surgery are generally the same as with the implantation of any other intraocular lens. Contact Beverly Hill Vision Institute to discuss whether aspheric intraocular lenses are right for you. Dr. Khodabakhsh will perform a thorough examination and fully inform you of any increased risk of complications you may have.
