ABSTRACT This case series evaluates the visual outcomes of two trifocal intraocular lenses, the ZFR00V and TNFT00, in cataract surgery patients. Nineteen patients (38 eyes) were bilaterally implanted with one of the two intraocular lenses. Postoperative assessments included uncorrected and corrected distance, intermediate, and near visual acuities, as well as patient-reported satisfaction and photic phenomena. Both intraocular lenses provided satisfactory visual performance for distance and intermediate vision. However, the ZFR00V intraocular lenses demonstrated superior near vision, particularly in the defocus […]

ABSTRACT Objective: To evaluate the effect of pterygium on different biometric intraocular lens calculation formulas. Methods: This is an interventionist, prospective, and non-randomized study. We included patients who underwent pterygium surgery and performed a biometric examination before and one month after surgery. We compared the mean variability between these measurements in each intraocular lens formula. We classified the patients according to the TAN staging system and evaluated the effect of pterygium magnitude on biometric variability. Results: We included 25 eyes […]

ABSTRACT The objective of this case report was to share the successful management of severe endophthalmitis, aiming at ocular integrity and visual acuity. A 73-year-old man presented with visual acuity of 20/30 in the right eye and 20/200 in the left eye. On the 21st day postoperatively after phacoemulsification in the left eye, he developed symptoms of endophthalmitis, including ocular discomfort, blurred vision, and whitish discharge. Despite negative cultures, his condition worsened, resulting in corneal perforation on the 31st day. […]

ABSTRACT Objective To evaluate intraocular lens power calculation and postoperative refractive errors in patients with high myopia undergoing cataract surgery, comparing predicted target refraction and actual postoperative refraction measured 30 days after surgery with SRK/T formula. Methods This retrospective analysis comprised 39 eyes of 31 patients undergoing cataract surgery through phacoemulsification with in-the-bag IOL implantation. Axial length was measured by partial coherence interferometry or immersion ultrasound biometry, with measurements greater than 26 mm and preoperative myopia greater than -6.0 D […]

ABSTRACT Objective: To evaluate the tear film and dry eye symptoms before and after phacoemulsification. Methods: Fifty-one patients diagnosed with cataracts participated in this clinical study (55% female; 78% white; 71.2 ± 6.5 years old; without the use of lubricating eye drops) and underwent phacoemulsification at a hospital in Aparecida (SP). Tear film analysis was performed by the tear film break-up test and dry eye symptoms were assessed by the Ocular Surface Disease Index, both before surgery and 30 and […]

ABSTRACT Throughout life, the lens produces new fibers arranged concentrically, which increase its anteroposterior diameter and weight, making its nucleus more compact and hardened. Hypermature cataract is an advanced stage of this fiber proliferation, which can trigger a variety of complications. Spontaneous rupture of the anterior lens capsule evolving with anterior displacement of the nucleus is a rare complication, with few cases published in the literature. We describe the case of a 68-year-old female patient, who presented spontaneous rupture of […]

ABSTRACT Objective To identify the epidemiological profile and visual benefit of the patient using the Unified Health System after cataract surgery. Methods This is a descriptive, cross-sectional and retrospective study with the analysis of medical records, between October and November 2020. We included 573 eyes of 319 patients that were selected for cataract surgery. Gender, age, cataract classification, pre-and post-surgery corrected acuity, smoking, presence of comorbidities, and previous ocular alterations were analyzed. Results Of the cataract surgeries performed, the mean […]

ABSTRACT Purpose: This study set out to examine the impact of surgical treatment of senile cataract on visual acuity and quality of life in patients operated in a public teaching hospital. Methods: Prospective study including patients aged over 60 years with clinical indications for cataract surgery treated at a medical residency service. The National Eye Institute Visual Function Questionnaire 25 was applied. Corrected distance visual acuity was measured before and after cataract surgery. Correlations between National Eye Institute Visual Function […]
