“…8,9 Diante deste fato, tem-se que a melhor abordagem terapêutica constitui-se da retirada do cristalino luxado para a cavidade vítrea através da vitrectomia associada a facofragmentação de todo material cristaliniano, evidenciando-se melhora efetiva na visão na maioria dos casos. 8,10,11 Após, optase pela realização de implante de lente intraocular. 8,10,11 Quanto mais cedo for a retirada do cristalino luxado, melhor a resolução do quadro e menores as complicações a longo prazo, tais quais glaucoma, uveíte, descolamento de retina e catarata.…”

The crystalline is a biconvex, avascular and transparent structure, located between the iris and the vitreous humor, in constant development throughout life. Patients who suffer trauma in the anterior segment of the eye may compromise some zonules, resulting in inclinations or displacements of the lens in relation to their usual location. This article presents the case of a patient seen in the emergency department of the Regional Hospital of São José (SC) with a crystalline dislocation in the vitreous cavity due to blunt trauma who, after four months, migrated to the anterior chamber spontaneously, being submitted to facectomy intra-capsular. Although severe traumas to the eye region cause crystalline's displacement to the vitreous cavity, especially blunt impacts, we did not find in the current literature registries of the association of dislocation of the crystalline lens to the vitreous cavity with subsequent migration to the anterior chamber, inferring that the case reported here was rare. We wish to improve knowledge and contribute to literary bases about crystalline dislocation, spreading singularities about this clinical occurrence.

“…Conventionally, surgical options involve either angle-supported anterior chamber intraocular lenses (ACIOLs), iris-xated and scleral-xated IOLs (SFIOL). [2] Scleral-xated IOLs (SFIOL) are mostly of two categories: trans-scleral suture-xated and sutureless intrascleral xated IOL. Scleral-xated IOLs are theoretically superior alternative over ACIOL as posterior chamber IOL (PCIOL) is placed in the original anatomical position.…”

Purpose to compare between intrascleral (Yamane Technique) and trans-scleral (ab externo technique) posterior chamber intraocular lens (PCIOL)implantation in cases of pediatric aphakia. Patients and methods: a prospective interventional study included 20 aphakic eyes < 18 years old with insufficient capsular support. Patients were randomly assigned into two groups; group (1) underwent sutureless intrascleral IOL implantation using Yamane technique and group (2) underwent trans-scleral IOL implantation (ab externo technique). Outcome measures included visual acuity (uncorrected UCVA& best corrected BCVA), astigmatism (corneal and IOL-induced), Keratometric readings, IOL state and any developed surgical complications. Patients were followed for at least 6 months. Results There was a statistically significant improvement in UCVA and BCVA at 6th month compared to preoperative values, without significant difference between the 2 groups. Corneal astigmatism was higher in group (2) whereas IOL-induced astigmatism was higher in group (1) with no statistically significant difference between the 2 groups in both parameters. IOL tilt was higher in group (1), but the difference was not significant. There was a statistically significant higher adjusted post-operative K2-reading in group (2) with no difference in adjusted post-operative K1-reading between the two groups. There was no statistical difference between the 2 groups regarding postoperative complications. Conclusion Both techniques for scleral fixation PCIOL resulted in comparable visual outcomes in pediatric cases with aphakia. Sutureless intrascleral fixed IOL results in lower corneal astigmatism with good IOL stability and centration.

“…The use of silicone oil as a tamponade agent in eyes with retinal detachment can also cause silicone oil-induced glaucoma [ 5 ]. Although various devices and techniques are available for the management of aphakia [ 6 – 8 ] and aniridia [ 9 ], some of these are not always effective over the long-term [ 10 , 11 ]. This report describes a safe and viable approach for the management of post-traumatic aniridia and aphakia.…”

Traumatic Aniridia and Aphakia Management with Iris Reconstruction Lens Using Gore-Tex Sutures, an Ab-Externo Approach

et al. 2020

Patient: Male, 55-year-old Final Diagnosis: Aphakia Symptoms: Decreased visual acuity • photophobia Medication:— Clinical Procedure: Lens implantation • vitrectomy Specialty: Ophthalmology Objective: Management of emergency care Background: A safer and more delicate approach is required for the management of a post-traumatic aphakia and subtotal aniridia. Case Report: A 55-year-old man was referred to our clinic with symptoms of decreased vision (hand motion) and photophobia in his right eye. This patient had previously undergone pars plana vitrectomy (PPV) for the management of blunt ocular trauma in the same eye. He was being treated with topical antihypertensives, due to silicone oil-induced glaucoma. On presentation, the best corrected visual acuity (BCVA) in his right eye was 20/40 and the intraocular pressure (IOP) in the same eye was 20 mmHg. Slit lamp examination of his right eye showed aphakia, aniridia, and some silicone oil droplets (fish eggs) following silicone oil extraction. His corneal endothelium and thickness were within normal limits. Dilated fundoscopic examination of the right eye revealed that the retina was attached with no signs of proliferative vitreoretinopathy (PVR). An artificial iris intraocular lens (IOL) was implanted, along with 4-point scleral fixation in conjunction with Gore-Tex sutures. After 6 months, the BCVA in his right eye was 20/40 and he had no symptoms of photophobia. The IOP in that eye was 15 mmHg while on treatment with dorzolamide-timolol eye drops. No suture-related or other serious complications were observed. The patient expressed satisfaction with the functional and cosmetic results. Conclusions: Modern vitrectomy combined with an artificial iris IOL and scleral fixation with Gore-Tex sutures in eyes lacking an iris and lens can provide long-term anatomic and functional restoration. Intraoperative IOP fluctuations and extra corneal damage can be avoided by lens preparation with the sutures using a small incision ab-externo approach.
