[Determination of visual function after implantation of intraocular lens]
Objective:
To understand whether the binocular visual function could be restored after posterior chamber intraocular lens (IOL) implantation.
Methods:
The visual function including corrected vision, simultaneous perception, fusion, stereoacuity, aniseikonia and retinal correspondence point were determined for 50 cases (64 eyes) after the surgery.
Results:
The corrected visual acuities were 0.6 or better. Visual acuities of 1.0 or better were achieved in 65% and 0.6-0.9 in 35% of the eyes. All patients obtained simultaneous perception and fusion function. The near stereoacuity of 50 cases showed foveal stereoacuity < or = 60 seconds in 23 cases (46%), macular stereoacuity 80-200 seconds 10 cases (20%) and peripheral stereoacuity 400 seconds 17 cases (34%). The far stereoacuity of 50 cases comprised 34 cases of foveal stereoacuity (68%), 9 cases of macular stereoacuity (18%) and 7 cases of peripheral stereoacuity (14%). The postoperative retinal correspondence points were normal. There was no aniseikonia in 35 cases, except 15 cases of aniseikonia which was within normal tolerable limits.
Conclusion:
When binocular corrected vision is > or = 0.4 with ocular alignment, the binocular visual function could be restored for varying degrees.
