Cataract surgery is one of the most cost-effective health interventions, since its economic benefits considerably exceed the cost of treatment. [131] [132] The 1998 World Health Report estimated 19.34 million people were bilaterally blind due to age-related cataracts, and that cataracts were responsible for 43% of all cases of blindness. This ...
Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye.

One needs fluid in the eye always. An AC maintainer also be used instead. D-One haptic externalized. Fig 6 : Subluxated three piece IOL glued into place- Part 2.

The disadvantage is that the eye's ability to change focus (accommodate) has generally been reduced or eliminated, depending on the kind of lens implanted. [citation needed] Some of the risks that were found in the early 2000s during a three-year study of the Artisan lenses were: [citation needed] a yearly loss of 1.8% of the endothelial cells,

Often, to avoid losing the monocle, a string or wire is connected to the wearer's clothing at one end and, at the other end, to either a ...
