摘　　要：We present a novel confocal laser method （CLM） for precise testing of the dioptric power of both positive and negative intraocular lens （IOL） implants. The CLM principle is based on a simple fiber-optic confocal laser design including a single-mode fiber coupler that serves simultaneously as a point light source used for formation of a collimated Gaussian laser beam, and as a highly sensitive confocal point receiver. The CLM approach provides an accurate, repeatable, objective, and fast method for IOL dioptric power measurement over the range from 0 D to greater than ±30 D under both dry and in-situ simulated conditions.We present a novel confocal laser method （CLM） for precise testing of the dioptric power of both positive and negative intraocular lens （IOL） implants.
