CATARACT
A cataract is a clouding of the lens, which may cause blurry vision, difficulty reading in low light, and excessive glare when driving at night. As a cataract progresses, one may experience rapid changes in the eyeglass prescription. Cataract surgery is an elective outpatient procedure, and should be considered when the vision begins to affect daily activities. Dr. Burris removes the hazy lens by phacoemulsification, utilizing sound waves (ultrasound).
Depending on the anatomy and needs of the patient he implants several types of lenses. Monofocal lenses provide clear vision at one distance, and most patients with these lenses only require reading glasses. Toric lenses are astigmatism correcting, and typically used in patients with high orders of corneal astigmatism. Multifocal lenses provide clear vision at multiple distances for those wishing to be less dependent on glasses, however they may increase the experience of glare and halos.
