Objective: To evaluate the correlation of optical biometry and target with variable ages, anterior chamber depth, axial length, R1/K1 and R2/K2 established by two optical biometry devices in patients with cataract. Methods: The study included the analysis of 348 medical records, from which 503 cataract eyes were selected, which underwent evaluation by the optical biometric devices IOL Master 700 and Lenstar LS 900 in the period of April to July 2017. Data collected were: age, anterior chamber depth, axial length, […]

Objective: The main purpose of this article is to compare the predictability of biometric results and final refractive outcomes expected in patients undergoing cataract surgery through phacoemulsification with and without associated trabeculectomy. Methods: Cataract patients who have undergone phacoemulsification surgery alone (control group) or associated with trabeculectomy (study group) screened. All surgeries were performed following standard protocol. For enrollment, biometrics calculated by IOL Master (Carl Zeiss Meditec, Inc.) biometry, refraction and intraocular pressure (IOP) before and after surgery were required. […]

We report a case of keratis infection after cataract phacoemulsification with intraocular lens implantation in a 65-year-old female patient. The patient initially underwent cataract surgery on the right eye. Intraocular inflammation appeared on the second post-operative day and was initially treated as Toxic Anterior Segment Syndrome (TASS). The inflammation was reduced and vision improved initially but very aggressive and progressive keratitis destroyed the cornea due to the delay in correct diagnosis. Aspergillus flavus was isolated from a biopsy.The infection was […]

The authors report a case of a 69 year-old woman who developed persistent vertical deviation and diplopia after extracapsular cataract surgery and had a positive past history of thyroid disease. The authors emphasize the need of for detailed orbit propedeutics in order to rule out restrictive strabismus associated with post-facectomy diplopia.

This article presents a review of the principles and clinical applications of the Scheimpflug principle in the anterior segment imaging. By providing a three-dimensional image of the anterior segment, this technology provides elevation and curvature data of the anterior and posterior surfaces of the cornea, pachymetric mapping, the total refractive power of the cornea and the anterior segment biometry. For the refractive surgery sub-specialty, this approach improves the ability to identify cases at risk of ectasia, as well as the […]

Objective: To investigate the association between falls and quality of life in elderly individuals with cataract. Methods: This was an observational and cross-sectional study carried out in the Federal District, Brazil, with a sample of 38 community-dwelling elderly individuals, who were divided into two groups: falling elderly (n=18) and non-falling elderly (n=20). The NEI-VFQ-25 was used as a tool to assess the patient overall health and the quality of life related to visual health. Sample characterization was performed by descriptive […]

The Christmas tree cataract is a rare type of lens opacification characterized by deposits of needle-shaped polychromatic cortex deep in the core, that can be isolated or associated with other opacities. We report and record, through photographs, two cases of this type of lens opacity.

Purpose: To evaluate the changes of corneal biomechanical after femtosecond laser – assisted cataract and to compare the parameters derived by Corvis ST between standard phacoemulsification and femtosecond laser – assisted in cataract surgery Methods: This is a prospective study. 151 eyes of 127 patients were under went cataract surgery. 75 eyes of 65 patients were with femtosecond laser–assisted (FS)(Alcon Len Sx, Aliso Viejo,USA) and 76 eyes of 62 patients with standard phacoemulsification (SP) (Alcon Infinit, Fort Worth, USA). Lens […]
