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.
