Background and Objective: This study aimed to investigate glaucoma progression following secondary intraocular lens (SIOL) implantation by surgical approach. Patients and Methods: This was a single-center retrospective study of 440 eyes that received SIOL implantation, including scleral-sutured, scleral-fixated, anterior chamber, and sulcus-fixated. Glaucoma progression was defined as new diagnosis, procedure for intraocular pressure (IOP) control, or IOP elevation ≥ 24 mmHg or ≥ 5 mmHg above baseline requiring additional medications. Risk factors were assessed using multivariable analysis. Results: Mean age at surgery was 71.3 years and 29.3% of patients had prior glaucoma. Overall, 33.2% developed glaucoma progression. Prior glaucoma (hazard ratio 2.08 [95% CI 1.47–2.94], P < .001) and cystoid macular edema (1.63 [1.06–2.52], P = .026) were associated with glaucoma progression on multivariable analysis. There was no difference in glaucoma progression between scleral-sutured, scleral-fixated, anterior chamber, or sulcus-fixated implantation techniques. Conclusion: Our results suggest that surgeons should use their preferred SIOL implantation technique but closely monitor postoperative IOP.

Purpose: The study compares refractive outcomes of secondary intraocular lens (SIOL) surgery performed by vitreoretinal, anterior segment, and both surgeons. Methods: Eyes included in this study underwent SIOL surgery from 2012 to 2024 and had a final postoperative visual acuity of 20/50 or better. Regression analysis compared refractive outcomes, and chi-squared analysis compared complications between subspecialty of SIOL surgeons. Results: A total of 94, 104, and 80 eyes were included in the retina surgeon, anterior segment surgeon, and combo surgeon cohorts, respectively. There was no significant difference in error between target and final postoperative spherical equivalence between retina and combo ( P = 0.079), retina and anterior segment ( P = 0.135), or anterior segment and combo cohorts ( P = 0.567). There was no significant difference in number of eyes with final spherical equivalence within 1 diopter of target spherical equivalence between retina and combo ( P = 0.136), retina and anterior segment ( P = 0.061), or anterior segment and combo cohorts ( P = 0.783). The retina cohort had higher postoperative corneal edema than the combo ( P = 0.017) and the anterior segment cohorts ( P = 0.035). The combo cohort had more postoperative retinal detachment than the anterior segment cohort ( P = 0.046). Conclusion: In eyes with good final vision, retina and anterior segment surgeons have similar refractive outcomes after SIOL surgery.

Purpose: Mohs micrographic surgery with immunohistochemistry allows for same-day comprehensive margin assessment of melanoma in situ prior to subspecialty reconstruction. This study describes the oncologic and reconstructive outcomes of eyelid and periorbital melanoma in situ and identifies risk factors for complex reconstructive demands. Methods: Retrospective case series of all patients treated with Mohs micrographic surgery with immunohistochemistry for melanoma in situ affecting the eyelids or periorbital region from 2008 to 2018 at a single institution. Tumors were assigned to the eyelid group if the clinically visible tumor involved the skin inside the orbital rim. Reconstructive variables were compared between the eyelid and periorbital cohorts. Results: There were 24 eyelid and 141 periorbital tumors included. The initial surgical margin for all tumors was 5.34 ± 1.54 mm and multiple Mohs stages were required in 24.2% of cases. Eyelid tumors included more recurrences (p = 0.003), and the average defect size was larger (14.0 ± 13.3 cm2 vs. 7.7 ± 5.4 cm2, p = 0.03). Risk factors for complex reconstruction included: initial tumor diameter >2 cm (odds ratio [OR]: 3.84, 95% confidence interval [CI]: 1.95–7.57) and eyelid involved by initial tumor (OR: 4.88, 95% CI: 1.94–12.28). At an average follow-up of 4.8 years, there were no melanoma-related deaths and 1 local recurrence (0.6% recurrence rate). Conclusions: Mohs micrographic surgery with immunohistochemistry achieves excellent local control rates for periocular melanoma in situ. An initial surgical margin of 5 mm is frequently insufficient to achieve clear margins. The resulting defects are large, and the complexity of reconstruction can be predicted by tumor size and clinical involvement of eyelid skin.
