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.
