Aim: To evaluate the effect of cataract surgery on frequency doubling technology (FDT) perimetry in patients with co-existing cataract and glaucoma.
Methods: In this consecutive prospective cohort study 27 patients with open angle glaucoma scheduled for cataract extraction alone or combined with trabeculectomy were enrolled. All patients underwent FDT threshold C-20 visual fields within 3 months before and 3 months after surgery. Changes in mean deviation (MD) and pattern standard deviation (PSD) were evaluated. Additionally, changes in best corrected logMAR visual acuity (VA), intraocular pressure (IOP), and number of glaucoma medications were also studied.
Results: 22 patients completed the study. VA improved after surgery, from 0.47 (SD 0.19) to 0.12 (0.17) (p<0.001). The visual indexes changed after cataract extraction: MD improved (from -10.9 (SD 4.6) dB to -7.0 (4.6) dB; p<0.001) while PSD worsened (from 7.1 (SD 3.5) dB to 8.5 (3.8) dB; p = 0.001).
Conclusion: In patients with co-existing cataract and glaucoma, examined with FDT, MD improved and PSD worsened after cataract surgery. Global indexes of FDT should be interpreted with caution in patients with glaucoma and cataracts.

Background Recommendations regarding long-term postoperative activity are intended to prevent adverse events, but no common policy or best practice exists among ophthalmologists for pediatric patients. We surveyed ophthalmologists on their postoperative guidelines after the one-month postoperative period following childhood cataract and glaucoma surgeries. Methods A 28-question anonymous Qualtrics survey was distributed via listservs and social media.

Background: Endothelin is a potent vasoconstrictor and contributes to the regulation of vascular perfusion. Aberrant endothelin-1 (ET-1) levels in aqueous humor have been reported across a variety of vascular diseases of the eye, including glaucoma. These findings suggest that dysregulation of ET-1 production may contribute to glaucoma pathophysiology.

Purpose: We aimed to evaluate the effects of autologous serum plus artificial tears on corneal sensation and tear film stability in patients with mild to moderate xerophthalmia after cataract surgery.
Methods: A total of 150 patients with mild to moderate xerophthalmia after one-time cataract surgery from March 2022 to September 2023 were selected and randomly divided into a control group (n = 75) and a study group (n = 75). The control group was treated with artificial tears (polyvinyl alcohol eye drops), while the study group was given autologous serum plus artificial tears.

Purpose: To describe a three-phase surgical approach for managing progressive visual decline in a patient with myopia magna and a history of epikeratophakia.
Methods: A 55-year-old woman with previous epikeratophakia surgery in both eyes experienced progressive visual deterioration. The three-phase approach included: (1) removal of the epikeratophakia lenticule, (2) cataract extraction with intraocular lens implantation, and (3) transepithelial topography-guided photorefractive keratectomy (trans-PRK).
