ABSTRACT
BACKGROUND: To describe the refractive outcomes of eyes with high regular corneal astigmatism undergoing age-related cataract surgery. METHODS: Astigmatic patients who underwent cataract surgery with implantation of high-power XY1AT HOYA® toric lenses (IOLs) (≥ T5) between March 2020 and June 2022 were included. Patients were divided into 2 groups based on the type of Total Corneal Astigmatism (TCA) used for the toric IOL calculation: group 1 = TCATK- 700 (TCA measured by the Iol Master 700®) and group 2 = TCAAK- 700 (TCA estimated from the anterior keratometry of the Iol Master 700® and using the Abulafia-Koch regression). The best-uncorrected (UDVA) and corrected (CDVA) distance visual acuity, subjective spherical equivalent (SSEq) and subjective residual cylinder (SRC) were assessed at 1 month. The predictability (centroid [CEPA] and mean absolute error in predicted astigmatism [MAEPA]) of the 2 TCA assessment methods was analyzed. RESULTS: 96 eyes of 74 patients were included. In the whole cohort, the UDVA was 0.14 ± 0.19 logMAR, the CDVA was 0.04 ± 0.07 logMAR. Postoperative SSEq was - 0.24 ± 0.53D. Postoperative SRC was - 0.48 ± 0.56D. The UDVA, SSEq and SRC did not significantly differ between groups. The MAEPA was significantly better with TCAAK-700 compared to TCATK-700: 0.58 ± 0.52D versus 0.65 ± 0.55D (p = 0.01). No significant difference was observed for the CEPA (p(x) = 0.09, p(y) = 0.19). CONCLUSIONS: XY1AT HOYA® toric IOLs are a very good alternative even in case of high toricity. Residual astigmatism predictability is high, it would be better with TCAAK- 700. This data should be confirmed with a larger sample of patients.
ABSTRACT
PURPOSE: Steroid-induced ocular hypertension (OHT) occurs in about a third of cases after dexamethasone implant (DEXi) intravitreal injection (IVI), for which treatment discontinuation may be required. The aim of this study was to assess the benefit of selective laser trabeculoplasty (SLT) in patients who developed transient OHT after DEXi injection to prevent subsequent steroid-induced OHT peaks during reinjections. METHODS: A real-life, retrospective, and observational study was conducted to assess the intraocular pressure (IOP) after SLT in steroid responders after DEXi injection (IOP > 21 mmHg). Were analyzed: IOP 1 and 2 months after SLT, maximum IOP (IOPmax) after each new DEXi IVI, and the number of prophylactic hypotensive treatments needed at the time of DEXi reinjections. RESULTS: Thirty-five eyes of 29 patients were included. The mean macular edema follow-up duration was 38.4 ± 28.4 months. SLT was performed after a mean number of 6.3 ± 4.7 DEXi IVIs. After SLT, the IOPmax measured after the first reinjection was lowered by 36.6 ± 14.7% (p < 0.0001). The mean number of hypotensive treatments was 2.1 ± 0.9 before versus 1.5 ± 0.8 after SLT. The post-reinjection lowering in OHT peak was maintained during the subsequent 3 DEXi IVIs: - 29.1 ± 25.5% (p = 0.0009), - 35.8 ± 13.1% (p = 0.0078), and - 45.4 ± 8.6% (p = 0.0312) after the second, third, and fourth DEXi reinjections. SLT allowed continuing injections in 88.6% of patients. CONCLUSION: The use of 180° SLT in this indication could be an effective therapeutic alternative to control steroid-induced OHT and safely continue DEXi injections.

PURPOSE: The aim of this study was to compare the functional and anatomical effectiveness of photodynamic therapy (PDT) versus proton beam therapy (PBT) in a real-life setting for the treatment of circumscribed choroidal hemangioma. METHODS: A total of 191 patients with a diagnosis of circumscribed choroidal hemangioma and treated by PBT or PDT were included for analyses. RESULTS: The 119 patients (62.3%) treated by PDT were compared with the 72 patients treated by PBT. The final best-corrected visual acuity did not differ significantly between the two groups (P = 0.932) and final thickness was lower in the PBT compared with the PDT group (P = 0.001). None of the patients treated by PBT needed second-line therapy. In comparison, 53 patients (44.5%) initially treated by PDT required at least one other therapy and were associated with worse final best-corrected visual acuity (P = 0.037). In multivariate analysis, only an initial thickness greater than 3 mm remained significant (P = 0.01) to predict PDT failure with an estimated odds ratio of 2.72, 95% confidence interval (1.25-5.89). CONCLUSION: Photodynamic therapy and PBT provide similar anatomical and functional outcomes for circumscribed choroidal hemangioma ≤3 mm, although multiple sessions are sometimes required for PDT. For tumors >3 mm, PBT seems preferable because it can treat the tumor in only 1 session with better functional and anatomical outcomes.

PURPOSE: To compare the impact of total corneal astigmatism (TCA) estimated with the Abulafia-Koch formula (TCAABU) versus measured by Total Keratometry (TK), swept-source optical coherence tomography (OCT) coupled with telecentric keratometry (TCATK) on the refractive outcomes after cataract surgery with toric intraocular lens (IOL) implantation. METHODS: Two hundred one eyes of 146 patients who underwent cataract surgery with toric IOL implantation (XY1AT; HOYA Corporation) were included in this single-center, retrospective study. For each eye, TCAABU (estimated from the anterior keratometry values measured with the IOLMaster 700 [Carl Zeiss Meditec AG]) and TCATK (measured using TK IOLMaster 700) were entered into the HOYA Toric Calculator. Patients were operated on based on TCAABU. For each eye, centroid and mean absolute error in predicted residual astigmatism (EPA) were calculated according to TCA used (TCAABU or TCATK). The cylinder power and the axis of the posterior chamber IOL were compared. RESULTS: The mean uncorrected distance visual acuity was 0.07 ± 0.12 logMAR, the mean spherical equivalent was 0.11 ± 0.40 D, and mean residual astigmatism was 0.35 ± 0.36 D. Mean centroid EPA was 0.28 D at 132° with TCAABU and 0.35 D at 148° with TCATK (P(x) < .001; P(y) < .01). Mean absolute EPA was 0.46 ± 0.32 D with TCAABU and 0.50 ± 0.37 D with TCATK (P < .01). In the with-the-rule astigmatism subgroup, a deviation from the target of less than 0.50 D was achieved in 68% of eyes with TCAABU versus 50% of eyes with TCATK. The proposed posterior chamber IOL was different depending on the calculation methods used in 86% of cases. CONCLUSIONS: Both calculation methods showed excellent results. However, the predictability error was significantly reduced when TCAABU was used compared to TCATK measured with the IOLMaster 700 in the whole cohort. Finally, TCA was overestimated by TK in the with-the-rule astigmatism subgroup. [J Refract Surg. 2023;39(3):171-179.].
