Abstract
To evaluate the postoperative visual outcomes and complications of posterior iris fixated intraocular lens (IFIOL) implantation for pediatric traumatic cataract.
A retrospective clinical audit was performed of all the pediatric traumatic cataract patients who underwent lens removal and iris fixated lens implantation due to inadequate capsular support with or without corneal tear repair between January 2009 and December 2013. Data were collected and analyzed on the preoperative and postoperative visual outcomes and complications.
Twenty-five children (25 eyes; 21 males and 4 females) were enrolled with the mean age of 11 ± 4.0 years. There were 72% of eyes that underwent primary cataract removal with IFIOL implantation. Twenty-eight percent of eyes underwent corneal tear repair prior to intraocular lens (IOL) implantation. Preoperative best corrected visual acuity (BCVA) was hand motion in 32% eyes, counting fingers in 24%, and perception of light in 44%. Postoperative BCVA of 0-0.2 logarithm of minimum angle of resolution was reported in the 64% of eyes. One eye developed secondary glaucoma, one eye underwent re-enclavation, and none developed retinal complications.
Posterior IFIOL implantation resulted in an improved visual outcome, low incidence of postoperative complications, and is a good alternative to other IOL, in the cases of pediatric traumatic cataract without adequate capsular support.

All the surgeries were performed by a single surgeon. Informed written consent was obtained from the parents of all the children. The patients were excluded if they had retinal pathologies and cases where a posterior approach with IFIOL implantation would affect the final visual outcome. The study adhered to all the principles of the Declaration of Helsinki 2000.</p><p>Data were collected on the nature and duration of the injury, uncorrected visual acuity, and best corrected visual acuity (BCVA) using logarithm of the minimum angle of resolution (LogMAR) charts, intraocular pressure (IOP), and anterior and posterior segment assessment, including B-scan in hazy media. Fellow eye keratometry and axial length readings were used for IOL power calculation in the eyes with corneal tear/status of post tear repair. The iris fixated (claw) was IOL implanted in all cases (Excel optics, Chennai, India, Model No: PIC 5590 or Model No: PIC 5580). This IOL is a modified version of Dr. Worst and Dr. Daljit Singh Model. It can be implanted in either ways as it has no angulations [<xref ref-type="fig" rid="F1">Figure 1</xref>].</p><fig id="F1" position="float"><label>Figure 1</label><caption><p>Iris fixated intraocular lens: Overall length of 9 mm or 8 mm, biconvex optic size of 5.5 mm or 5 mm, a constant 117.2: Postoperative round pupil</p></caption><graphic xlink:href="MEAJO-23-215-g001"></graphic></fig><p>The IOL power was undercorrected in the anticipation of a myopic shift as the child ages and the eye grows.<xref rid="ref5" ref-type="bibr">5</xref> Children <2 years were undercorrected by 20%, between 2 and 5 years by 10%, 5-8 years by 5%, 8-10 years by 2.5%, and children older than 10 years were targeted for emmetropia. All the surgeries were performed under general anesthesia. Corneal/corneoscleral tear was repaired using 10-0 nylon interrupted sutures. Cataract removal and IFIOL implantation were performed as a primary or secondary procedure through a superior 5.5-6 mm scleral tunnel. The anterior capsule was stained with tryphan blue dye. Posterior synechiae, when present, was released. Anterior continuous curvilinear capsulorhexis was performed using a bent 26-gauge needle and Utrata capsule forceps in eyes with intact anterior capsule under sodium hyaluronate (1.4%). In cases with a ruptured anterior capsule, capsulotomy was performed. Lens matter was aspirated using irrigation-aspiration cannula. Closed chamber anterior vitrectomy and superior peripheral iridectomy were performed with automated vitrector in all cases. Two paracentesis at 3 o'clock and 9 o'clock positions were made. IFIOL (claw) was inserted into the anterior chamber with the help of Macpherson forceps. The optic was held with a claw IOL forceps; one haptic (claw) was tilted down (at three o'clock) and gently pushed under the iris. A fine rod (30-gauge) was passed through the paracentesis on the same side, the haptic behind the iris was tilted up to produce an indent on the iris, and the iris tissue was enclaved into the claw with a gentle push of the rod. Similarly, enclavation was performed on the other side (nine o'clock). All patients were treated with steroid antibiotic, homatropine eye drops, and oral steroids for a week.

Complications of SFIOL include suture breakage with IOL subluxation, dislocation, endophthalmitis, and retinal detachment.<xref rid="ref3" ref-type="bibr">3</xref><xref rid="ref12" ref-type="bibr">12</xref><xref rid="ref13" ref-type="bibr">13</xref> Alternately, IFIOLs, invented by Dr. John Worst and Dr. Daljit Singh, have emerged as safe IOLs, have an improved design, are easy to implant, and offer better safety and efficacy with low dislocation rates compared to other IOLs.<xref rid="ref4" ref-type="bibr">4</xref> Posterior IFIOL enclavation is a better option than other IOL implantation techniques due to the decrease in surgical time with minimal complications, greater distance from the endothelium, and the position is similar to the physiological crystalline lens.<xref rid="ref4" ref-type="bibr">4</xref><xref rid="ref14" ref-type="bibr">14</xref> We found similar results in our study with minimal complications. Vision improved in all the cases except for one eye that had perception of light + vision. Preoperatively, no eyes had BCVA better than one logMAR. However, at last postoperative visit, 16 of 25 eyes had BCVA between 0 logMAR and 0.2 logMAR, six eyes had 0.3-0.6 logMAR, and two eyes had 0.7-1.0 logMAR. These outcomes suggest a remarkable improvement in the visual acuity, postoperatively, in our study and are similar to Yen <italic>et al</italic>.'s results.<xref rid="ref12" ref-type="bibr">12</xref> Complications of posterior IFIOL implantation in the adults include pupil irregularity, macular edema, transient elevated IOP, and spontaneous IOL dis-enclavation.<xref rid="ref15" ref-type="bibr">15</xref> In our study, only one eye had an elevated IOP of 24 mmHg after a month; which may be attributed to preexisting trauma or ocular inflammation. One eye had dis-enclavation at 1-month, iris atrophy and oval pupil, indicating the low incidence of postoperative complications in the current study. None of our patients in our study had CME or retinal detachment. This study is limited by its retrospective, noncomparative nature, lack of endothelial cell analysis, and short term follow-up. Longer term follow-up is required to determine the status of the IOL over time.</p><p>The posterior IFIOL implantation was associated with improved visual outcomes with the low incidence of postoperative complications and can be used as an alternative to other IOLs in the children with traumatic cataracts, with inadequate capsular support.</p><sec id="sec2-2"><title>Financial support and sponsorship</title><p>Nil.</p></sec><sec id="sec2-3"><title>Conflicts of interest</title><p>There are no conflicts of interest.</p></sec></sec></body><back><ack><title>Acknowledgment</title><p>The authors would like to thank the Management - Sankara Eye Hospital, Staff - Sankara Eye Hospital, Dr. S.
