Accommodation in primate eyes after implantation of refilled endocapsular balloon.
OBJECTIVE
To restore accommodation after crystalline lens removal.


METHODS
The crystalline lens of one eye of each of four primates was removed by phacoemulsification. Each operated-on eye underwent endocapsular silicone balloon implantation followed by filling with an organosilicone mixture. Seven months postoperatively, the anterior chamber depth and refractive power changes were measured before and after topical application of 4% pilocarpine.


RESULTS
In the refilled eyes, the average anterior chamber depth reduction was 0.50 mm and the average maximal myopic change was 6.74 diopters.


CONCLUSIONS
After lens removal, measurable accommodation was restored in the eyes with the endocapsular balloon filled with an organosilicone mixture.
