Presbyopia: no perfect option yet, surgeon say

ORLANDO, Fla. — None of the three approaches currently used to correct presbyopia is an ideal solution; standard, said Michael Knorz, MD, This three current approaches to surgical correction of presbyopia are 1.monovision, 2.pseudoaccommodation and 3. restoration of accommodation. Monovision can be achieved using any refractive procedure. Conductive keratoplasty offers some advantages over other similar hyperopic correction measures. “Distribution of heat with CK is more homogenous in the tissue. Scars are more predictable, effects more lasting.While monovision works to correct presbyopia, it involves a compromise, It reduces stereopsis, reduces distance vision and does not offer perfect near vision and also that in the United States, monovision has a 70% patient acceptance rate, but in Germany, the acceptance rate is “more like 10% to 20%.Pseudoaccommodation can be achieved with multifocal IOL implantation, To date, results with this approach are imperfect, The compromise is slightly reduced distance vision, not perfect near vision, halos and ghosting. It's not acceptable to everyone, but it is a feasible option.” Restoration of accommodation might be achieved with several surgical procedures, “but all the data is experimental.
