• Purpose To report ultrasound biomicroscopic (UBM) findings of glued transscleral-fixated posterior chamber intraocular lenses (IOLs) in eyes with inadequate capsules. Setting Dr. Agarwal's Eye Hospital and Eye Research Centre, Chennai, India. Design Case series. Methods Eyes with glued IOLs for inadequate capsule support were examined with UBM. Optic tilt was measured in relation to the iris plane. Haptic location, iris–IOL contact, vitreous incarceration, and central anterior chamber depth (ACD) were measured and correlated clinically with vision and refractive error. Results The mean follow-up was 24.6 months ± 14.3 (SD). Of the 46 eyes, 8 (17.4%) showed optic tilt and 38 (82.6%) showed no optic tilt. Of 92 haptics examined, 85 (92.4%) were in the ciliary sulcus and 7 (7.6%) in the pars plicata. There was no significant association between the presence of optic tilt and haptic location ( P =.585, chi-square test). The mean ocular residual astigmatism (ORA) was 0.5 ± 0.2 diopter (D). There was no significant difference in ORA between eyes with tilt and eyes without tilt ( P =.079). There was no significant correlation between ORA and IOL position. There was no correlation of optic tilt and postoperative vision or cylinder. Other features included iris–IOL contact (6.5%), vitreous incarceration (5.4%), and ACD difference ( P =.002). Conclusions No significant IOL optic tilt affecting the postoperative vision was detected with glued transscleral-fixated IOLs. The technique reliability was good, with the haptics located in the intended position in more than 90% of eyes. Financial Disclosure Dr. Amar Agarwal is a paid consultant to Staar Surgical Co.
