Abstract

PURPOSE: To compare the visual outcomes and complication rates of sutureless cannula-based intraocular lens scleral (SCILS) fixation performed with 25-gauge (25 G) versus 27-gauge (27 G) instrumentation.

METHODS: A retrospective chart review of consecutive cases of eyes without capsular support that underwent SCILS fixation of a three-piece intraocular lens. Sutureless cannula-based intraocular lens scleral fixation was performed by transconjunctival use of either 25-G or 27-G trocar cannulas. During postoperative follow-up evaluations, visual acuity and intraocular pressure were measured, and slit-lamp and indirect ophthalmoscopy examinations were performed to assess for development of known complications.

RESULTS: A total of 69 eyes underwent 25 G (27 eyes) or 27 G (42 eyes) SCILS fixation. The mean preoperative logarithm of the minimum angle of resolution visual acuity trended toward improvement from 0.95 ± 0.68 (20/178 Snellen equivalent) to 0.67 ± 0.64 (20/94 Snellen equivalent) for 25 G group at 1 year. Similar trend toward visual acuity improvement was seen in 27 G group with a mean preoperative logarithm of the minimum angle of resolution visual acuity of 1.43 ± 0.94 (20/538 Snellen equivalent) improving to 0.86 ± 1.00 (20/145 Snellen equivalent) at 1 year. Statistically significant improvement was seen as early as postoperative week one for 27 G group (P < 0.01), whereas statistically significant worsening was noted at the same time in 25 G group (P = 0.01). There was a statistically significant reduction in intraocular lens displacement (P = 0.01) and need for reoperation (P = 0.01) in 27 G group.

CONCLUSION: Compared with 25 G SCILS fixation, eyes managed with 27 G SCILS fixation experienced more rapid visual acuity improvement. In addition, there was a lower rate of complications including intraocular lens displacement and need for reoperation.
