ABSTRACT
Purpose: The purpose of the study is to evaluate the visual and patient-reported outcomes of patients undergoing cataract surgery with implantation of an extended depth of focus (EDOF) intraocular lens (IOL) who were not primarily good candidates for multifocal IOL implantation. Methods: Retrospective analysis of data from 30 eyes (23 patients) undergoing cataract surgery with implantation of one of two EDOF IOLs (follow-up: 37.9 ± 16.2 months) and prospective observational study including 106 eyes (78 patients) implanted with one of 6 different EDOF models (follow-up: 8.0 ± 7.7 months). Patients recruited had one of the following conditions: monofocal IOL implanted in the fellow eye, previous corneal refractive surgery, mild and nonprogressive maculopathy or glaucoma, age > 75 years, amblyopia, or previous vitrectomy. Results: In the retrospective phase, significant improvements were found in uncorrected distance (UDVA), corrected distance (CDVA), and corrected near visual acuity (CNVA) (p ≤ 0.013), with a nonsignificant trend to improvement in uncorrected near visual acuity (UNVA). A total of 90% of patients were completely to moderately satisfied with the outcome achieved. In the prospective phase, significant improvements were found in UDVA, CDVA, UNVA, and CNVA (p ≤ 0.032), with a total of 85.5% of patients being completely to moderately satisfied (dissatisfaction 3.3%). In both phases, extreme difficulties were only reported by a limited percentage of patients for performing some near vision activities. Conclusions: EDOF IOLs seem to be a viable option for providing an efficient visual rehabilitation with good levels of patient satisfaction and spectacle independence associated in patients that are not primarily good candidates for multifocal IOL implantation.
ABSTRACT
Purpose: : To analyze the ocular surface changes in eyes after the withdrawal of anti-glaucomatous drugs when non-penetrating deep sclerectomy (NPDS) is performed. Methods: Thirty-one patients (33 eyes) diagnosed with glaucoma that underwent NPDS were included in this prospective study. The control group included 33 eyes. Four variables were studied using Keratograph 5M (K5M): ocular hyperemia (OH), non-invasive tear film break-up time (NI-BUT), lower tear meniscus height (LTMH), and meibography. LTMH was also measured using the anterior segment module of a Spectralis Fourier-domain optical coherence tomography (FD-OCT) instrument. Moreover, an evaluation of corneal and conjunctival staining was performed. In the glaucoma group, five visits were carried out: pre-surgery, 1 week after surgery, and 1 month, 3 months, and 6 months after surgery. In control groups, examinations were performed in only one visit. In addition, patients were asked to answer two questionnaires: Ocular Surface Disease Index (OSDI) and National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) before and 6 months after surgery. Results: Before NPDS, eyes showed worse objective data than healthy control subjects (P ≤ 0.049). In this group, a significant improvement was observed in questionnaire responses (P < 0.001), LTMH-FD-OCT (P = 0.037), LTMH-K5M (P = 0.025), K5M-OH (P = 0.003), NI-BUT (P = 0.022), and conjunctival and corneal staining (P < 0.001). No significant differences were observed between groups in FD-OCT and K5M LTMH, NI-BUT, corneal-conjunctival staining, nor in the most OH sector values at 6 months (P ≥ 0.62). Conclusion: A significant improvement in the ocular surface was observed 6 months after NPDS, suggesting that the withdrawal of the topical anti-glaucomatous treatment had a beneficial effect on the subjects.
