The Duet-Kelman lens: A new exchangeable angle-supported phakic intraocular lens.
OBJECTIVE
We describe a new model of angle-supported phakic intraocular lens, the Duet-Kelman lens, the design of which incorporates two separate supporting parts. The haptic and the optic are separately implanted and then fixed together inside the eye. The lens allows optic or haptic exchange depending on the anatomical, refractive, and visual outcome of the patient. Results of the initial pilot study are presented.


METHODS
Three patients (three eyes) were implanted with the Duet-Kelman lens and were followed for a minimum of 6 months. Surgery was performed under topical anesthesia.


RESULTS
Surgery was feasible through a 2.5-mm incision, without complications. Refractive and visual results were stable in all eyes. Haptic exchange was done in one eye that developed pupil ovalization.


CONCLUSIONS
In this pilot study of three eyes, the Duet-Kelman phakic intraocular lens offered small incision size and potential exchange of the haptic or the optic.
