Purpose: The aim of this study was to evaluate the outcomes of a simplified, fixed surgical dosage calculation for uncomplicated, horizontal, concomitant strabismus in adults. Methods: Outcomes analysis of a fixed-dose calculation method for uncomplicated, horizontal, concomitant strabismus in adults (≥18 years) wherein 1-mm recession/resection equals 2 PD for lateral rectus and 3 PD for medial rectus. This was a retrospective case series. Results: The mean age of the patients was 28.50 ± 8.43 years, the mean amount of preoperative deviation was 35.16 ± 9.97 PD, the mean expected correction was 36.26 ± 9.49 PD, and the mean correction achieved was 35.92 ± 10.74 PD. There were 22 monocular exotropias, six monocular esotropias, eight alternate divergent squints, and two alternate convergent squints. There were 20 cases of sensory strabismus (54.28%). There was no statistically significant difference between the expected correction and correction achieved ( P = 0.519), meaning that our fixed-dose calculation method was effective. Thirty-five out of 38 patients had successful outcomes as per our criteria of less than 10-PD deviations from straight in primary position. Therefore, the success rate achieved by this procedure was 92.10%. There was no statistically significant correlation between age and the amount of deviation ( P = 0.611) Conclusion: Our case series had a high postoperative success rate in terms of motor alignment. It is hoped that this simplified, fixed-dosage calculation method would help the numerous novice strabismus surgeons, make their starting steps easier and give them the confidence to do strabismus surgeries. They can modify the dosages later as per their own experiences.

Breakage of an intraocular lens (IOL) haptic during implantation is a rare complication of cataract surgery. We report here a case of a broken fragment of a trifocal IOL playing hide and seek and causing corneal edema repeatedly after an uneventful phacoemulsification and preloaded trifocal IOL (AT LISA tri 839MP) implantation. It was ultimately removed successfully and the patient achieved good vision. It is postulated that the broken piece of IOL migrated to and fro, from sulcus to anterior chamber. The breakage of IOL should also be kept in mind in the case of postoperative corneal edema when other causes have been ruled out.
