[Clinical research on movement of intraocular contact lens during accommodation].

Objective: To study the movement of intraocular contact lens (ICL) during accommodation.

Methods: Forty one eyes of 41 consecutive patients implanted ICL to correct high myopia were collected. The visual acuity and accommodation power were checked before and after the surgery.

Accuracy and repeatability of direct ciliary sulcus diameter measurements by full-scale 50-megahertz ultrasound biomicroscopy.

Background: Phakic intraocular lens (pIOL) implantation has been a popular means for the treatment of high ametropia. Measurements of ciliary sulcus diameter is important for pIOL size determining. But till now, no perfect system can directly measure it.
