Surgical Reversal of Presbyopia
Surgical Reversal of Presbyopia
Background: The loss of accomodation occurring in all individuals aftrer the age of 40 has been attributed to the gradual hardening of the crystalline lens.
Purpose: To restore the nature near accommodative focusing ability of all phakic individuals without altering the distance refractive error.
Method: Based on clinical investigation by Dr. Ronald A. Schachar, it has been established that the natural lens of the human eye continues to grow throughout life and eventually encroaches on the area of the zonules and ciliary muscle complex reducing their ability to transmit the necessary forces responsbile for accommodation.
Result: By inserting a small polymethylmethacrylate (PMMA) segment within the sclera overlying the cilliary body in each of the four oblique quadrants of the globe, the tension between the lens, zonules, and ciliary muscle is re-established and normal accommodation is restored.
