Efficacy of Adding Sodium Hyaluronate Eye Drops to Tobramycin and Dexamethasone in the Treatment of Post-Cataract Surgery Dry Eye Disease: A Retrospective Analysis and Prospective Questionnaire Assessment.

Purpose: This study aimed to compare the efficacy of using a combination of antibiotic and corticosteroid eye drops to using the same combination in addition to sodium hyaluronate eye drops. Patients and Methods: This study included patients who underwent phacoemulsification for age-related cataract and presented to the ophthalmology department or outpatient clinic of the two hospitals in the study with DED during the period from January 2020 to January 2023. The study involved a two-pronged approach in which we retrospectively analyzed the prospectively maintained data of the patients and prospectively called the patients for an evaluation of the dry eye impact on vision-related function. The study patients were recruited from two hospitals. During the study period, patients who were treated with a combination of antibiotic and corticosteroid eye drops were enrolled in Group A, and those who were treated with the same combination with sodium hyaluronate eye drops were enrolled in Group B. Results: The present study included 143 patients with post-phacoemulsification DED. Group A included 70 patients, and Group B included 73 patients. There was statistically significant improvement 4 weeks after treatment (p < 0.05) in the two groups. Comparing the two groups showed statistically significant improvements in group B compared to group A (p < 0.05). Assessment of the overall efficacy outcome revealed a statistically significant high percentage of cure (35.6% vs 1.4%) and high effectiveness (42.5% vs 13.6%) and a low percentage of effectiveness (21.9% vs 74.3%) and ineffectiveness (0.0% vs 5.7%) in Group B compared to Group A (p < 0.001). Conclusion: Combining sodium hyaluronate eye drops with tobramycin and dexamethasone eye drops yielded obviously better efficacy outcomes compared to using tobramycin and dexamethasone eye drops alone.

Safety and efficacy of implantable phakic contact lens versus implantable collamer lens in myopia correction.

Background: Phakic intraocular lenses (pIOLs) have proven to be excellent substitutes for excimer laser keratorefractive surgery in certain situations. We aimed to assess the efficacy and safety of two pIOLs, the implantable collamer lens (ICL V4c) versus the implantable phakic contact lens (IPCL V2), for myopic correction. Methods: In this prospective randomized clinical trial, we allocated eligible eyes with myopia > - 6 diopters into IPCL or ICL implantation groups, each including 100 eyes of 100 individuals. Preoperative and postoperative assessments at 3, 6, and 12 months included measurements of the spherical equivalent (SE), uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), intraocular pressure (IOP), maximum keratometry (K1), minimum keratometry (K2), mean keratometry (Kmean), anterior chamber depth (ACD), anterior chamber angle (ACA), and endothelial cell density (ECD). Results: The groups had comparable demographic characteristics and baseline visual and anatomical values (all P > 0.05). The UCDVA, BCDVA, and SE of the two groups were comparable at baseline and at all postoperative follow-up examinations (all P > 0.05). Both groups experienced significant improvements in UCDVA, BCDVA, and SE at three months postoperatively (all P = 0.001), and measurements remained stable for up to 12 months. Keratometry readings were comparable between the groups over the follow-up period and remained unchanged at all visits (all P > 0.05). The ACA in the ICL group was significantly decreased at three months postoperatively (P = 0.001) and then widened significantly at 6 and 12 months (both P = 0.001). In the IPCL group, the postoperative ACA was significantly decreased at three months (P = 0.001) and was comparable to that in the ICL group (P > 0.01). However, at the 6- and 12-month postoperative visits, the ACA was significantly narrower in the IPCL group than in the ICL group (both P = 0.001). The ACD in both groups was decreased at three months postoperatively (both P = 0.001) and remained stable until the end of the study. The ECD remained comparable between the groups at all postoperative visits (all P > 0.05). We did not observe a significant ECD reduction in either group at any postoperative follow-up visit (all P > 0.05). We encountered no serious complications in either group. Conclusions: ICL and IPCL had comparable safety and efficacy outcomes in terms of anterior chamber morphometrics, visual and refractive results, and corneal parameters. Further multicenter randomized clinical trials with longer follow-up periods, larger sample sizes, and measurement of additional anterior chamber and corneal morphometrics, vault, and other vision parameters are needed to verify these findings.
