Observation Of Tertiary Visual Function Before And After Laser Corneal Refractive Surgery For Monocular Vision Design

To observe the changes in third level visual function before and after laser corneal refractive surgery with monocular vision design using a synoptoscope.

There is limited research on the reconstruction of tertiary visual function after monocular surgery and its impact on postoperative visual quality recovery.

This study included 30 patients undergoing laser corneal refractive surgery with monocular vision design. Inclusion criteria: Age range from 40 to 50 years old; No organic lesions in the eyes; When preoperative refractive error is completely corrected, both subjective and objective strabismus angles are within -3 ° to+5 °. Use a synoptoscope (model: YZ23B) to record preoperative full correction, simultaneous vision, fusion vision, and stereoscopic vision at 1, 3, and 6 months post surgery.

There was no statistically significant difference in tertiary visual function between preoperative total correction and postoperative 3 and 6 months (P>0.05). The fusion visual range one month after surgery was smaller than that of preoperative total correction and postoperative 3 and 6 months, and the difference was statistically significant (P<0.05), but there was no statistically significant difference in simultaneous and stereoscopic vision (P>0.05).

After stable laser corneal refractive surgery with monocular vision design, there was no significant change in the third level visual function compared to before surgery. But postoperative reconstruction of the third level visual function requires a certain amount of time.
