Opacification2
- Early in the development of age-related cataract, the power of the lens may be increased, causing near-sightedness (myopia), and the gradual yellowing and opacification of the lens may reduce the perception of blue colors. (eyewell.ca)
- Posterior capsule opacification (PCO) is a common postoperative complication of extracapsular cataract surgery, which is caused by the proliferation and migration of lens epithelial cells and can affect long-term visual outcomes significantly. (bvsalud.org)

Anterior capsule1
- After performing cataract surgery with a low-flow technique, I would administer a miotic agent to reduce the pupil's size as much as possible and then place a 10-0 Prolene suture on a double-armed STC-6 needle (both from Ethicon, Inc.). To ensure that I engaged the edge of the torn iris, I would use micrograspers to hold the iris and to avoid the anterior capsule. (crstoday.com)
