The calculation of IOL power in patients with high axial myopia using the third or the fourth generation formulas help in improvement of the accuracy of the calculation and decreasing the post operative refractive error. SRK/T formula showed the lowest mean error, however, there was not statistically significant difference between the three formulas used, neither in the overall performance, nor in axial length subcategories.

Purpose. To assess visual results and complications of a modified technique of posterior chamber intraocular lenses (PC IOLs) in aphakic eyes without scleral flaps. Methods. Modified one-haptic scleral fixation was performed in one eye each of 25 patients with aphakia and insufficient capsule support. Follow-up period was six months. Outcome measures included best-corrected visual acuity, intraocular pressure (IOP), and postoperative complications. Results. The study included 15 males and 10 females. The preoperative best-corrected visual acuity (BCVA) ranged from 5/60 to 6/9. The operation time ranged from 25 to 45 minutes (mean 35.25 ± 5.34 min). Anterior vitrectomy was performed in 12 cases (48%). There was no major IOL decentration. The final BCVA ranged from 6/36 to 6/9. Seven cases (28%) showed postoperative glaucoma, five cases (20%) had temporary hypotony, and hyphema in 2 eyes (8%). No cases of suture erosion, postoperative endophthalmitis, retinal detachment, or IOL dislocation were detected. Conclusion. This technique of one-haptic scleral fixation of posterior chamber IOLs is a good choice in presence of insufficient capsule support. It reduces the operation time, achieves the IOL stability, and minimizes postoperative suture-related complications.

There was no significant difference in IOP reduction, surgical complications and visual outcomes between subscleral trabeculectomy, or deep sclerectomy with intraoperative mitomycin C in combination with phacoemulsification and intraocular lens implantations in patients with primary open-angle glaucoma.

Background: Cataract surgery alone has gained more acceptance as an alternative surgical approach for primary angle closure glaucoma management. This view was supported by the recent advances in phacoemulsification and intraocular lenses, which possess a greater safety and a quicker visual recovery, in addition to a substantial reduction of intraocular pressure, deepening of the anterior chamber, and widening the filtration angle. Aim of Study:The current study is to evaluate the effects of phacoemulsification and Intraocular Lens (IOL) implantation versus phacotrabeculectomy on IOP in eyes with PACG and coexisting cataract. Patients and Methods:The current study is a randomized control study that has been conducted on 40 patients who were diagnosed to have PACG and chronic narrow angle glaucoma. Patients were recruited and followed in the Department of Ophthalmology, Mansoura University and were divided into 2 groups; (Group A) patients who underwent phacoemulsification and IOL implantation, and (Group B) patients who underwent phacotrabeculectomy and IOL implantation.

Purpose: To evaluate and compare Corneal endothelial changes following Divide-and-conquer versus stop-and-chop Phacoemulsification techniques Methods: The study was conducted on 90 senile cataract eyes that were prepared to have phacoemulsification and posterior chamber intraocular lens (IOL) and at Mansoura ophthalmology center in the period from May 2019 till June 2020. The eyes were divided into two groups; each group had 45 eyes. One group subjected to 'divide & conquer' phacoemulsification technique. The other group subjected to 'stop & chop ' phacoemulsification technique. Full history and ocular examination have been done for all individuals. Specular microscopy has also been done pre-operative and post-operative at one week, one month and three months to assess the count of the endothelial cell and Corneal Pachymetry.Results: Compared to pre-operative mean ECC the decrease is statistically significant in the mean ECC post-operatively in the two groups at three months (P <0.05*)). There was also decrease in statistically significant in the mean ECC in the 'divide & conquer ' group post-operatively compared to pre-operative mean ECC at one week (P <0.014*) and at one months (P <0.012*).Nevertheless, there was statistically insignificant difference (after one week P=0.163, P=0.133 after one month and after three months P=0.256). Conclusion:One-week post-operation showed the most significant decrease in cell count of endothelia in the two groups compared to pre-operative mean ECC ('divide & conquer' group about 7.1%, 'stop & chop' group about 4.7%). One month showed less cell loss of endothelia in the two groups. Three months showed the least decrease compared to pre-operative mean ECC ('divide & conquer ' group about 9.9%, 'stop & chop ' group about 8.7%). There was statistically insignificant difference although more endothelial loss (about 9.9%) occur in 'divide & conquer ' group when compared with 'stop & chop ' group (about 8.7%)
