Abstract
Background: Advances in surgical procedures have allowed for minimally invasive cataract surgery procedures such as phacoemulsification with foldable intraocular lens implantation. However, the ideal foldable intraocular lens which is cheap, stable and effective has yet to be determined. This study attempts to assess the stability and effectiveness of Tecsoft Sterile Foldable acrylic Intraocular Lenses for primary visual correction following uncomplicated phacoemulsification surgery.
Materials and Methods: Retrospective analysis of case records of 174 eyes of 114 patients who had undergone phacoemulsification with insertion of Tecsoft Sterile Foldable Acrylic Intraocular lenses from September to November 2016 was done for 2 years after surgery. Demographic parameters of patients and stability and efficacy of lenses in providing good postoperative outcome was assessed in terms of visual acuity, rates of postoperative iritis, postoperative rise of intraocular pressure, corneal edema, IOL decentration, PCO formation and anterior capsule fibrosis.
Results: Excellent visual and refractive outcomes and stability were demonstrated. At postoperative visit 4 week 96.6% of subjects achieved a Snellen best-corrected distance visual acuity (BCVA) of 6/6 to 6/18 (Log MAR 0.0 - 0.5), and 98.3% of subjects achieved a BCVA of 6/18-6/60 (LogMAR 0.50 - 1.0) or better. At final visit in 2 years, after Neodymium:yttrium aluminum garnet (Nd:YAG) capsulotomy for Posterior Capsular Opacification (PCO) where necessary, 98.3% patients had a BCVA of 6/6-6/18 (0.0 - 0.5) and all patients had a BCVA of better than 6/60 (Log MAR 1.0). Adverse events were infrequent and were consistent with incidences generally reported with cataract surgery.
Conclusion: Tecsoft Sterile Foldable Acrylic Intraocular lens (Hydrophilic, Posterior Chamber) was found to be efficient both in terms of visual outcome and stability and results were comparable to other hydrophilic lenses.
