Clinical Study of Scleral Fixated Intraocular Lens Implantation in Blunt Ocular Trauma

Aim: to assess visual outcome and complications associated with SFIOL implantation in traumatic lens subluxation/ dislocation cases.

Methods: This is a retrospective study of 45 patients who were managed for traumatic dislocation/subluxation of clear or cataractous lenses from June 2019 to July 2020 in a Krishna hospital, Karad, Satara. All cases underwent anterior vitrectomy/3 port pars plana vitrectomy + removal of lens and ab externo 2 point scleral fixation with rigid or foldable sfiol. In posteriorly dislocated/subluxated lens, vitrectomy was done and the lens was removed using pick forceps and retrieved by hand shake technique. In anteriorly dislocated cataractous lens, the lens was removed through the tunnel incision.

Results: Majority of the patients were between 55-65 years of age with male pre-ponderance (73.3%).Out of 45 cases, 21 cases (46.6%) were traumatic dislocated lens and 24 cases (53.3%) were traumatic subluxated lens. The mean preoperative BCVA was 0.13 ± 0.24 logMAR, which improved 0.39 ± 0.366 logMAR postoperatively (P <0.0001 ).Preoperatively BCVA in logMAR in 39 cases (86.6%) was 0.3 or better, 6 cases (13.3%) was 0.3 to 1.0 . Postoperatively BCVA in logMAR in 21 cases (46.67%) was 0.3 or better, 24 cases (53.3%) was 0.3 to 1. P-value is 0.00057 which is significant. Early postoperative complications noted were raised intraocular pressure in 12 cases (26.6%), corneal edema in 9 cases (20%), vitreous hemorrhage in 8 cases (17.7%) and hypotony in 3 cases (6.67%).Late postoperative complications were persistent elevation of intraocular pressure in 10 cases (22.2%), cystoid macular edema in 3 cases (6.67%), epiretinal membrane in 3 cases (6.67%).

Conclusion: In every horrendous case, long haul follow-up is needed to distinguish confusions and start treatment at the most punctual.
