[Spherical aberration influence in visual function after cataract surgery: prospective randomized trial].

PURPOSE: We compare the contrast sensitivity and visual acuity obtained with an anterior surface modified prolate intraocular lens (Tecnis Z9000) with the contrast sensitivity and visual acuity obtained with a standard acrylic foldable intraocular lens (Acrysof SA60 AT). METHODS: In this prospective trial, 64 patients presenting for cataract surgery were randomized to receive in both eyes either the Tecnis Z9000 intraocular lens or the the Acrysof SA60AT intraocular lens: 32 Tecnis Z9000 and 32 Acrysof SA60AT. Visual acuity and contrast sensitivity were monocular and binocularly tested in all of them preoperatively and three months after surgery. RESULTS: The Tecnis Z9000 intraocular lens provided statistically significantly better monocular (Tecnis group: 0.85; Acrysof group: 0.78; p < 0.01) and binocular (Tecnis group: 0.95; Acrysof group: 0.86; p < 0.02) visual acuity. The contrast sensitivity mean was also greater in Tecnis group in monocular and binocular conditions, but without statistical signification. CONCLUSION: Visual acuity and contrast sensitivity after cataract surgery improved in both groups. But monocular and binocular visual acuity was statistically significantly better only in Tecnis group. The contrast sensitivity mean values were greater in Tecnis group but without statistically significant differences.

[Light-induced maculopathy in cataract surgery].

CASE REPORT: Case 1: An 82-year-old man who underwent an uncomplicated phacoemulsification and IOL implantation (Tecnis Z 9000 lens) in his right eye under topical anaesthesia. Surgery lasted 14 minutes. Case 2: A 60-year-old woman with bilateral advanced primary open angle glaucoma who underwent an uncomplicated phacoemulsification and IOL implantation (Tecnis Z 9000 lens) in her right eye under peribulbar anaesthesia. Surgery lasted 36 minutes. One month after surgery both patients noted a para-central scotoma and impaired vision. Fluorescein angiography in both cases revealed retinal pigment epithelial changes compatible with intra-operative light-induced maculopathy. DISCUSSION: Light-induced maculopathy has been reported following cataract surgery. Whether physical properties of these new polysiloxane lenses contribute to retinal susceptibility to phototoxicity under certain light conditions needs to be elucidated.

[Acute posterior multifocal placoid pigment epitheliopathy associated with Graves-Basedow's disease].

CLINICAL CASE: We present a case of a 40-years-old woman with an acute posterior multifocal placoid pigment epitheliopathy (APMPPE) associated with recent instauration hyperthyroidism symptoms. A Graves' disease was diagnosed and the patient was initially controlled with antithyroid drugs. The epitheliopathy evolution was relatively favourable without relapse. Two years later a thyroidectomy was performed. DISCUSSION: We have not found in the literature any APMPPE case associated with Graves' disease. We only found an APMPPE case associated with a subacute thyroiditis. Little is known about the APMPPE causes, it could be that placoid epitheliopathy and Graves' disease had a common autoimmune origin. We can not forget that our finding could be only a matter of chance.
