Abstract Details

Purpose:

To analyze the changes of binocular vision function before and after intraocular lens (ICL) implantation, to investigate the importance of binocular visual function in ICL implantation.

Setting:

chongqing

Methods:

Retrospective study. High myopia patients with abnormal binocular visual function after ICL implantation were included in the study. The parameter of binocular visual functions were compared and analyzed including positive relative accommodation/negative relative accommodation (NRA/PRA), amplitude of accommodation (AMP), accommodation of facility (AF), binocular cross-cylinder (BCC), far and near horizontal accumulation and dispersion, accommodative convergence/accommodation (AC/A), convergence near points (NPC) and etc.

Results:

The binocular visual function of patients with ICL implantation were gradually restored to normal level through reasonable training including adjustment, aggregation and fusion.

Conclusions:

Patients with high myopia often have abnormal binocular visual function before ICL implantation, including: 1.Insufficient accommodation, poor flipper and other abnormalities, leading to vision fatigue; non-sustainable; 2.Non-strabismic diplopia, dizziness and others produced fusion decompensation; 3.Double image, line skip and others caused by abnormal convergence; Therefore, the preoperative design should pay attention to visual function examination before ICL implantation, at the same time strengthen visual function training in time after ICL implantation, in order to achieve clarity, comfort and lasting visual quality, and enhance the satisfaction of ICL patients.
