Abstract:
The purpose of this study was to investigate the function of stereo visual acuity in patients after phacoemulsifications and intraocular lens implantation. Mensuration of stereopsis with laser holographic stereovision test chart was done in 80 cases who had undergone phacoemulsifications and intraocular lens implantation. In this group, 43 patients were male, 37 were female .Ages of the patients were 52 to 81 years. Single eye operation was done in 18 cases, while both eye operation in 62 cases. The corrected vision was all over 0 4 in both eyes.In the 80 cases 67 (83 7%) had near stereopsis and 13 cases (16 3%)did not have; 71 cases (88 8%) had distance stereopsis and 9 cases (11 2%)did not have. Function of stereopsis weakens gradually following aging and is closely related with vision. The function of sterovision would recover to varying degrees after phacoemulsifications and intraocular lens implantation. Recovery of distance stereopsis was better than that of near stereopsis.The results of this study show that the status of stereopsis is an important index to evaluate the curative effect in patients after phacoemulsifications and intraocular lens implantation.
