Astrocytic tumors occur in the retina or in the optic disc usually as a part of tuberous sclerosis complex or other phacomatosis and their isolated occurrence is rare. The authors present two adult patients in whom the diagnosis of intraocular astrocytoma was established but no signs of phacomatosis were revealed.(Eur J Ophthalmol 2004; 14: 350-4).

Purpose To demonstrate an unusual mechanism of iatrogenic, central descemetorhexis (DMR) during cataract surgery and subsequent rare spontaneous visual acuity improvement within 2 months after inadvertent surgical complication. Patients and Methods A 81 year old woman underwent cataract surgery complicated by the loss of a 4.8X4.75 mm diameter central area of Descemet membrane. Perioperative video recording documented the DMR formation during continuous curvilinear capsulorhexis creation. Results Postoperatively, severe corneal edema with folds in the remaining Descemet membrane were observed. The patient was managed conservatively. The corneal edema gradually resolved over 2 months with improving of visual acuity from counting fingers to 20/20. Conclusion Unlike Descemet membrane detachment, descemetorhexis is a rare complication after intraocular surgery. The case report identifies a previously unknown mechanism of DMR formation during anterior capsulotomy creation. Loss of Descemet membrane may be managed conservatively in an otherwise healthy cornea with good final visual outcome without the need for surgical intervention.

According to our findings, both entities overlap one another, even in some characteristics considered to be distinguishing. The question arises, therefore, whether the strict separation of these nosological entities can indeed be determined with one hundred percent accuracy.

Purpose. To evaluate the incidence of laser enhancement following cataract surgery and refractive lens exchange (RLE) with FineVision Micro F trifocal lens implantation (PhysIOL, Liège, Belgium). Methods. Retrospective study of patients who had undergone cataract or RLE surgery and had received a FineVision Micro F intraocular lens. Laser enhancement of residual refractive error was determined. Visual acuity (VA) assessments were performed before and after surgery: uncorrected distance VA (UCDVA), best-corrected distance VA (BCDVA), uncorrected near VA (UCNVA), plus preoperative and postoperative spherical equivalent (SE) assessments. Results. Of the 1129 eyes from 596 patients, 61 (5.4%) required laser enhancement to correct residual refractive error (by group: 30/679 eyes [4.4%] cataract; 31/450 eyes [6.9%] RLE). Eleven eyes received FemtoLASIK; 50 eyes received PRK. Mean UCDVA before laser enhancement was 0.26±0.19 logMAR and 0.24±0.14 in the FemtoLASIK and PRK groups, respectively. After laser enhancement, these were 0.04±0.05 logMAR and 0.13±0.19, respectively; BCDVA values were 0.00±0.00 logMAR in the FemtoLASIK group and 0.06±0.11 in the PRK group. Laser enhancement improved UCNVA (Jaeger) from 2-3 to 1-2 in both groups. Enhancement reduced preoperative SE of -0.39±0.99 D and -0.53±0.58 D (FemtoLASIK and PRK groups, respectively) to 0.24±0.36 D and 0.04±0.47 D. Conclusions. The FineVision Micro F trifocal lens is an effective solution for gaining increased spectacle independence. The incidence of residual refractive error requiring laser enhancement is low, and laser procedures are a safe and effective solution for improving the quality of vision and patient satisfaction. Synopsis. Laser enhancement rates and outcomes were determined following cataract / refractive lens exchange surgery that used a trifocal IOL. Enhancement was safe and effective and rates were low (5.4%).
