Manual cataract extraction via a subconjunctival limbus oblique incision for mature cataracts.

Yang J, Lai P, Wu D, Long Z - Indian J Ophthalmol (2014)

Bottom Line: Intraoperative complications included hyphema in 3 eyes (2.7%), iridodialysis in 2 eyes 1.8%), posterior capsular rupture and zonular dialysis in 2 eyes (1.8%).At the 3-month follow-up, 91% patients achieved a best-corrected visual acuity of 20/20 or better, the mean of surgically induced astigmatism was -0.62 ± 0.41 Diopters and endothelial cell loss was 4.2%.Average surgical time was 3.75 min per case.

ABSTRACT

Aims: To report the technique and outcomes of sutureless manual cataract extraction via a subconjunctival limbus oblique incision for mature cataracts.

Materials and methods: This retrospective study comprised of 112 eyes of 83 patients with mature cataract who all had manual cataract extraction via a subconjunctival limbus oblique incision. A transconjunctival tunnel is fashioned with a 3.0 mm keratome, 0.5 mm behind the limbal vascular arcades. A limbal tunnel, with a transverse extent of 9 mm in the cornea and 7.0 mm in the limbus, is created beneath the conjunctival/Tenon's tissue using an angled bevel-up crescent blade. Outcome measures included visual acuity, intraoperative complications, surgically induced astigmatism, endothelial cell loss rate and surgery time.

Results: Self-sealing wound was achieved in 112 eyes (98.2%). The nucleus was delivered in whole in 108 eyes (96.4%). Intraoperative complications included hyphema in 3 eyes (2.7%), iridodialysis in 2 eyes 1.8%), posterior capsular rupture and zonular dialysis in 2 eyes (1.8%). At the 3-month follow-up, 91% patients achieved a best-corrected visual acuity of 20/20 or better, the mean of surgically induced astigmatism was -0.62 ± 0.41 Diopters and endothelial cell loss was 4.2%. Average surgical time was 3.75 min per case.

Conclusion: This subconjunctival limbus oblique incision has the potential to serve as safe and effective technique for mature cataracts.

Mentions: Postoperative 3-month data were available in 75% (84 eyes) of the cases. There are 67% patients at 1-day and 81% at the 3 months post-operative visit achieved a UCVA of 20/40 or better, 91% patients at the 3 months post-operative visit achieved a BCVA of 20/20 or better [Figs. 3 and 4]. Two eyes with a post-operative corrected visual acuity of 20/200 or worse had chorioretinal atrophic changes in the macula [Figs. 3 and 4].
