Purpose: To study the intraocular position and anatomic relationships of the PRL-III phakic refractive lens (PRL), a posterior chamber phakic intraocular lens (PCP IOL), in cases of hyperopia using ultrasound biomicroscopy (UBM).
Setting: Centro Oftalmológico Real Vision, Madrid, Spain, and Instituto de Investigaciones Oftalmológicas Ramón Castroviejo, Universidad Complutense, Madrid, Spain.
Methods: Eleven phakic hyperopic eyes of 6 patients who had PRL implantation were examined by UBM 1 month after surgery. The PRL position, PRL-crystalline lens peripheral distance, and central distance between the corneal endothelium and the PRL were measured.
Results: Eight eyes had both haptics on the zonule, 2 had 1 haptic in the sulcus and 1 on the zonule, and 1 had 1 haptic in the sulcus and the other in the ciliary body. The mean PCP IOL-crystalline lens peripheral distance in the minor axis was 239.7 microm +/- 179.4 (SD) and the mean PCP IOL-endothelium central distance, 2146.98 +/- 219.6 microm. Contact between the PCP IOL and crystalline lens was observed in 1 eye.
Conclusions: In this study of hyperopic eyes, the PRL was located on the zonule in most cases. However, the location of the haptics in the sulcus and contact between the PCP IOL and the crystalline lens that occurred in some cases suggest further study of possible long-term complications is needed.

Background: At present, silicone oil has been widely used in vitrectomy to deal with complex fundus diseases. Usually, cataract extraction is combined with vitrectomy. However, reducing the complications of silicone oil tamponade and facilitating the secondary implantation of intraocular lens (IOL) are still an urgent problem.

Purpose: To show the importance of measuring the angular distribution of straylight as an in vitro test for intraocular lenses (IOLs).
Methods: The optical integration method was implemented to measure the point spread function, up to 5.1°, of IOLs immersed in a wet cell.

Objectives: The aim of this study was to compare long-term outcomes of implants placed both in patients treated for periodontitis and in periodontally healthy patients (PHP).
Material And Methods: One hundred and twelve partially edentulous patients were consecutively enrolled in private specialist practice and divided into three groups according to their initial periodontal condition: PHP, moderately periodontally compromised patients (PCP) and severely PCP. Implants were placed to support fixed prostheses, after successful completion of initial periodontal therapy [full-mouth plaque score (FMPS) <25%, full-mouth bleeding score (FMBS) <25%].

Case Report: A 34-year-old man with severe myopia, presented with acute visual loss in his right eye. This occurred 3 hours after a posterior chamber phakic (PCP) intraocular lens (IOL) implantation, and was associated with a rhegmatogenous retinal detachment. Retinal retachment surgery was performed without complications, with the outcome showing good anatomical and functional results during a 2-year follow-up period.
