Visual rehabilitation in aphakia has been a challenge with a wide variety of surgical options available for ophthalmologist. We report the visual outcome with retropupillary iris claw lens secondary to intra operative complications and secondary implantation in aphakia. An interventional study on 4 eyes of 4 patients was conducted. Preoperative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome measure was best-corrected visual acuity and secondary postoperative complication was recorded at various intervals. All patients had visual acuity of ≥6/18 postoperatively. Sutureless retropupillary iris claw intraocular lens implantation is a good alternative of scleral-fixated intraocular lenses in aphakic patients.

Scleral Fixated Intraocular Lens

Introduction: This study was conducted to report the refractive and visual outcome after Scleral Fixated Intraocular Lens (SFIOL) implantation in children with nontraumatic ectopia lentis. Methods: Retrospective review of the medical records of 25 eyes of 15 patients who underwent SFIOL implantation in children with non-traumatic ectopia lentis. Results: The mean best corrected visual acuity (BCVA) before SFIOL implantation was 1.07 ± 0.9 logMar units [median: 0.9, Interquartile range (ΙQR): 0.415 to 1.555] which improved to 0.41 ± 0.33 logMar units (median: 0.22, ΙQR: 0.180 to 1.555) at two months postoperative follow up. In phakic group, the mean spherical refraction preoperatively was -12.04 ± 7.82 DS (dioptre sphere) (IQR: +16 to -5.875) and postoperatively was +0.93 ± 2.67DS (IQR: -0.375 to +2). In aphakic group, the mean spherical refraction preoperatively was +12.22 ± 2.05 DS and postoperatively was +1.2 ± 1.9 DS. The mean total astigmatism preoperatively was -6.44 ± 4.95 DC (dioptre cylinder) (median: 6, IQR: -10.50 to +2) and postoperatively was -1.47 ± 0.98 DC (median: -1.5, IQR: -2 to - 0.625 ). The mean IOL induced astigmatism was -1.01 ± 0.95 DC (median -0.75, IQR: -1.33 to - 0.25). The spherical refractive equivalent was within 2 Diopter (D) of the target refraction calculated preoperatively in 20 eyes and in five eyes it was more than 2 D. Conclusion: SFIOL implantation is associated with good visual outcome with a significant improvement in the refractive error. However, a longer follow up is required to assess the change of refraction and the stability of the SFIOL.

Background: The modern cataract surgery involves implantation of posterior chamber intraocular lens (PCIOL) when the posterior capsule is intact. However, in case of weak or no capsular support, PCIOL implantation is not possible. In such situations, implantation of secondary Iris claw lens (ICIOL) or Scleral fixated IOL(SFIOL) remains as treatment options. The aim of this study was to compare the efficacy of ICIOL and SFIOL in terms of visual outcomes and complications in aphakic patients. Methods: This prospective randomized study was done from January 2019 to December 2019. Forty aphakic patients fulfilling inclusion criteria, who attended the ophthalmology outpatient department of VVPF’s Medical college and hospital, Ahmednagar were included in this study. These patients were randomly divided into two groups such as Group 1 included 20 patients who underwent ICIOL implantation and Group 2 included 20 patients who underwent SFIOL implantation. The preoperative and postoperative evaluation was done with visual acuity, slit-lamp examination, IOP, fundus examination for the follow up period of 6 months. Results were analysed with Chi square test and t-test using SPSS software. Results: 85% ICIOL and 80% of SFIOL patients had final Best Corrected Visual Acuity (BCVA) of 6/18-6/6. Surgical time in ICIOL was significantly less than SFIOL group (p=0.00). Suture related complications were significantly more in SFIOL group. However, oval pupil and pigment dispersion were seen more in ICIOL group but were harmless. One patient in SFIOL group developed Cystoid Macular Edema (CME) which persisted till final follow up and 1 haptic of ICIOL was disenclavated which was re-enclavated. Conclusion: Comparable final visual outcome was found between ICIOL group and SFIOL group. However, Implantation of ICIOL required less surgical time with fewer complications and hence is a better alternative to SFIOL implantation in correction of aphakia.

Scleral Fixated Intraocular Lens

Introduction: Scleral fixated intraocular lens(SFIOL) implantation to correct aphakia offers superior visual rehabilitation in comparison to aphakic spectacles or contact lens. This study was done to evaluate a simplified technique of scleral fixation of posterior chamber intra-ocular lens (IOL) in terms of visual outcome and complications.Methods: This was a prospective study enrolling 23 eyes of 23 patients who underwent anterior vitrectomy followed by ab-externo sclera fixation of posterior chamber IOL using 10.0 polypropylene sutures from January 2016 to February 2017 in Nepal Eye Hospital.Scleral flap was made at 3 and 9'o clock meridian to cover the knots which prevent erosion of the knots through conjunctiva.  Main outcome measures were post-operative best corrected visual acuity and post-operative complications.Result: Best corrected visual acuity were 6/6 - 6/18 in 86.9% (n=20), 6/24 - 6/60 in 8.7% (n=2) and worse than 6/60 in 4.3% (n=1)at six months followup. The mean spherical equivalent before surgery was +10.60 diopter and -1.14 diopter post-surgery. The common indicationsfor scleral fixated intraocular lens weretrauma in 60.86% (n=14), surgical aphakia in21.73% (n=5), spontaneous posterior dislocation of lens in 13.0% (n=3) and subluxated intraocular lens in 4.34% (n=1). The common complications were astigmatism in 91.30% (n=21), decentered IOL in 4.34% (n=1) and uveitis in 4.35% (n=1).Conclusion: Ab-externosclerated fixated intraocular lens is a safe and effective method for visual rehabilitation with low post-operative risk.
