To correct a high hyperopia and irregular astigmatism secondary to multiples refractive surgeries in a 45 years old female, radial incisions suture and intraocular (IOL) Acrysof Toric lens was performed. To correct the residual refractional error a pseudophakic toric supplementary IOL was implanted over the primary one.The initial visual acuity (VA) was LogMAR 0,9 and the final VA was LogMAR 0,3. The implant of IOL supplementary over a primary toric IOL appears to be a good option, increasing the visual […]

OBJECTIVE: To describe the prevalence, location and causes of discontinuous capsulotomy during phacoemulsification cataract surgery. METHODS: Retrospective, consecutive, non-comparative study of 971 cataract surgeries – with discontinuous capsulotomy during surgery – performed from January 2009 to June 2010. RESULTS: it was observed a prevalence of 0.02% and capsule discontinuation occurring 100% of the time during the treatment of the nucleus. In 58.33% of the eyes the implant was done in the capsular bag and in 41.67% in the ciliary sulcus. […]

The intraocular lenses have been used in visual rehabilitation after cataract surgery since 1959 with a large success. However, biomaterial changes in the optic zone of these lenses have been described in the last years reducing visual acuity after surgery. This case reveals a significant snowflake opacification of the optic zone of polymethylmethacrylate intraocular lens followed by a discussion about this event and the indication for IOL exchange.

PURPOSE: The aim of this study is to compare visual acuity, contrast sensitivity, reading speed and quality of life of postoperative pseudophakic patients with unilateral or bilateral ReZoom multifocal intraocular lenses. METHODS: Comparative, prospective, not randomized study including 38 eyes of 24 patients were divided into a group with bilateral implantation (14 patients) and another with unilateral implantation (10 patients). The ophthalmological examination included visual acuity preoperative close, intermediate and far away, best corrected visual acuity, corneal topography, contrast sensitivity, […]

Purpose: To compare the ultrasound biometry measurements between immersion and contact techniques. Methods: The biometry was made in 60 eyes by the same examiner, using the contact and immersion techniques in each eye. Results: The lower mean axial length (23,16 mm) was found in the contact technique, and the greater (23,29) was found in the immersion technique, using the same probe. The lower mean standard deviation between recurrent measures in the same eye was found in the immersion technique, and […]

Purpose: Compare the OPD-scan results and the contrast sensitivity in patients who had implantation of the AcrySof SN60D3 multifocal IOL, the AcrySof SA60AT spheric monofocal IOL and the AcrySof SN60AT aspheric monofocal IOL. Methods: Thirty-two eyes received the multifocal IOL, 32 eyes received the spheric monofocal IOL and 32 eyes received the aspheric monofocal IOL. They were closely paired in age, sex, pre-operative wavefront analysis and contrast sensitivity. All patients was tested with the OPD-scan aberrometer, ETDRS chart at 100% […]

With aspherical intraocular lens (IOL), phakectomy could be more than removal of cataract, it also could means an improvement in optical quality of the eye. In this article, recently published studies on aspherical IOLs and exams to access optical quality were reviewed.

The authors present a case of intralenticular metallic foreign body, in a metallurgist patient, with lateness diagnosis. They describe the importance of clinical exame, the surgical technical that was used to remove the foreign body of the crystalline and necessity to divulge and promote preventive ways at the occupational and domestical ambients.
