Iol Dislocation

Intraocular lens (IOL) dislocation is an unusual but serious complication after cataract surgery. We are here to report a rare case which is nontraumatic IOL dislocated and prolapsed into the anterior chamber in a retinitis pigmentosa (RP) patient. Zonular weakness and capsular contraction are considered to be the main contributing factors of IOL dislocation in RP patients. Patients at risk should be recognized and managed accordingly intraoperatively or postoperatively.

Purpose: We report an unusual case of rapid and severe anterior capsular contraction associated with secondary intraocular lens (IOL) dislocation following cataract surgery in a patient with unspecified rod-cone dystrophy. Case Report: A 68-year-old woman with a history of uncharacterized bilateral rod-cone dystrophy presented with blurry vision 1 month after cataract surgery. Best corrected visual acuity was 20/40 in the operative eye. Slit-lamp exam showed severe anterior capsular phimosis limiting view of the fundus. Our patient underwent 2 sessions of Nd:YAG anterior capsulotomy with limited success. Limited anterior vitrectomy was then performed without success due to densely adherent capsular tissue to the anterior surface of the IOL and additional secondary IOL dislocation. She ultimately underwent pars plana vitrectomy, removal of the capsular bag, and IOL exchange with a scleral fixated IOL. Conclusion: Rapid and severe anterior capsular contraction following cataract surgery is rare but appears to be associated with rod-cone dystrophy.

Objective: To report a rare case of intraocular lens (ACIOL) opacification in the anterior chamber in an adolescent and to discuss the possible mechanism of its occurrence and the ways of its prevention. Case: A 16-year-old male underwent cataract surgery for developmental cataract with placement of a foldable posterior chamber IOL in the anterior chamber. There was subsequent opacification of the IOL, which was replaced by a scleral fixated posterior chamber intraocular lens. The post-operative visual acuity improved to 6/18. Conclusion: The posterior chamber IOL implanted in the anterior chamber can get opacified possibly due to postoperative intraocular inflammation.

Purpose: To report a case of Exophiala endophthalmitis after cataract surgery, which has not been reported previously in Korea.Case summary: A 70-year-old woman visited the hospital 7 days after cataract surgery in her right eye with unilateral vision impairment. At the time of the visit, visual acuity of the right eye was hand motion, and the fundus was not clearly observed due to numerous inflammatory cells with hypopyon in the anterior chamber. With an initial diagnosis of suspected bacterial endophthalmitis, vitrectomy was performed immediately with intravitreal injection of antibiotics and steroid. On day 14 after vitrectomy, inflammation in the anterior chamber and vitreous opacity worsened, and complete vitrectomy, including of the vitreous base, and removal of the intraocular lens and capsule was performed. Exophiala was detected in the biopsy specimen on day 6 after the second surgery, and the patient was discharged with a prescription for voriconazole eye drops. On day 23 after the second surgery, the best-corrected visual acuity in the right eye had improved to 1.0, and there was no evidence of endophthalmitis recurrence and no observed additional abnormal findings of the fundus until 6 months after second surgery.Conclusions: In a case of fungal endophthalmitis that occurred after cataract surgery, good results were obtained by vitrectomy involving complete removal of the peripheral vitreous body, including the intraocular lens and lens capsule, which was the basis for growth of the fungus in the early stage of endophthalmitis.

Intraocular Lens Calculation

In standard cataract surgery, one of the major goals is to reach target refraction. Based on keratometry measurements, axial length and anterior chamber depth, most of the intraocular lens calculation formulae are suitable to achieve this aim. Further evaluation of corneal refractive parameters like anterior and posterior corneal surface by Scheimpflug devices led to a significant enhancement of precision in astigmatic and post-refractive surgery cases.

Objective. The aim of this study was to evaluate possible risk factors for late intraocular lens (IOL) dislocation after routine cataract surgery. Material and Methods. A retrospective analysis of medical records of all the patients who were treated in the university hospital between 2011 and 2012 for late IOL dislocation requiring surgical management after routine cataract surgery was performed. In total, 58 patients (58 eyes) were included into the study. Results. The mean time between cataract surgery and late IOL dislocation was 67.8 months (SD, 34.9). A negative correlation was found between the patient age at cataract surgery and the time between cataract surgery and IOL dislocation (r=–0.29; P=0.042). Late in-the-bag dislocation occurred in 87.9% and late out-of-the-bag dislocation in 12.1% of the cases. Pseudoexfoliation was present in 56.9% and 42.9% of the eyes with in-the-bag and out-of-the-bag dislocation, respectively. The odds ratio for IOL dislocation within 43 months after complicated cataract surgery was 24.0 (95% confidence interval [95% CI] 4.5–127.4; P<0.001) and for in-the-bag IOL dislocation 24.9 (95% CI, 4.2–148.0; P<0.001). The odds ratio for in-the-bag IOL dislocation within 43 months after advanced cataract surgery was 18.8 (95% CI, 2.0–180.0; P=0.011). Moreover, in-the-bag IOL dislocation occurred earlier in the patients with past uveitis (P=0.020) or zonule laxity (P=0.037). Conclusions. Complicated cataract surgery increased the risk of both late in-the-bag and out-ofthe- bag IOL dislocation, and advanced cataract increased the risk of late in-the-bag IOL dislocation. The time to in-the-bag IOL dislocation shortens with pseudoexfoliation syndrome, advanced age, or past uveitis. These factors must be taken into account while planning a postoperative follow-up.

Capsular Support

Background: Following posterior capsular rupture (PCR) and vitreous loss during cataract surgery, sometimes there is inadequate support for implanting a conventional intra-ocular lens (IOL) in the capsular bag. Flexible openloop anterior chamber intraocular lens, trans-sclerally sutured posterior chamber intraocular lens and iris-claw lenses are the most acceptable alternatives in such a scenario. Objective: To review our experience with primary anterior chamber intraocular lens implantation at a District Hospital in Rajkot. Methods: Analysis of medical records of a consecutive series of primary anterior chamber intraocular lens implantations carried out at the G.T. Sheth Eye Hospital at Rajkot, from September 2011 to April 2013. Eyes with complicated or traumatic cataracts, ocular co-morbidity and cases of combined surgery were excluded from the analysis of visual outcome. Results: There were 70 cases of primary anterior chamber intraocular lens implantations during the study period. Posterior capsule rupture and resultant inadequate capsular support was the commonest indication for implanting the anterior chamber intraocular lens. Postoperatively 82.85% had a best corrected visual acuity of 6/12 or better. The commonest postoperative complications were cystoid macular oedema, recurrent iritis and persistent elevated intra-ocular pressure (IOP). Conclusion: Our results indicate a satisfactory visual outcome with primary implantation of anterior chamber intraocular lenses. Caution should be exercised when implanting an anterior chamber intraocular lens following complicated cataract surgery, particularly in the absence of appropriate capsular support.

Common Cause

We present a rare case of bilateral pseudoexfoliative deposits on both intraocular lens (IOL) implants in an 83-year-old woman with no other associated pathology, 5 years after cataract surgery. Pseudoexfoliation syndrome is the most common cause of secondary open-angle glaucoma worldwide and these deposits are usually found on the natural lens. The fact that pseudoexfoliative deposits have been found on IOL implants implies the need for a thorough examination in pseudophakic patients, for it could be the only sign of secondary glaucoma.
