Purpose: To investigate the clinical effects of different orientation and magnitude of cyclotorsion on the compensationcapacity of the WaveLight EX500 photorefractive keratectomy (PRK) platform. Methods: This retrospective study comprised 400 eyes of 200 patients who underwent bilateral simultaneousPRK due to compound myopic astigmatism. The subjects were separated according to the orientation of cyclotorsioninto incyclotorsion and excyclotorsion groups, and by the magnitude of cyclotorsion into group 1 (0.50to 2.50 degrees), group 2 (3.00 to 5.00 degrees), group 3 (5.50 to 7.50 degrees), and group 4 (8.00 to 9.50 degrees). Results: The mean magnitude of cyclotorsion was 3.50 ± 2.4 degrees (0.50 to 9.50 degrees) in the incyclotorsiongroup and 3.32 ± 2.3 degrees (0.50 to 9.50 degrees) in the excyclotorsion group (p = 0.617). The postoperativerefractive outcomes of the incyclotorsion and excyclotorsion groups were similar (p > 0.05 for all). Thepostoperative mean cylindrical refractive error was -0.32 ± 0.3 diopters (D, -1.25 to 0.00 D) in group 1, -0.47 ± 0.2D (-2.00 to 0.00 D) in group 2, -0.62 ± 0.2 D (-1.00 to -0.25 D) in group 3, and -0.91 ± 0.2 D (-1.50 to -0.50 D) ingroup 4 (p < 0.001). Preoperative cylindrical refractive error was positively correlated with magnitude of cyclotorsion(r = 0.125 and p = 0.013), which was also positively correlated with postoperative cylindrical refractiveerror (r = 0.600 and p < 0.001). Conclusions: Incyclotorsion and excyclotorsion can be equally compensable in the WaveLight EX500 PRKplatform for compound myopic astigmatism. A value of ≤2.50 degrees cyclotorsion magnitude was observedto be more compensable than higher degrees of cyclotorsion magnitude. Preoperative high astigmatism wasassociated with high cyclotorsion magnitude, which was also associated with a high degree of postoperativeastigmatism.

Purpose: To evaluate the changes in visual acuity (VA) and central macular thickness (CMT) after intravitrealdexamethasone (IVD) implantation in intravitreal bevacizumab (IVB) treatment-resistant cases with pseudophakiccystoid macular edema (PCME). Methods: This study included 10 PCME cases who underwent uneventful phacoemulsification and intraocularlens implantation with similar methods and six PCME cases referred to our hospital for treatment oflow VA after cataract surgery. Due to the persistence of PCME, both topical steroid and anti-inflammatorymedication were administered first, followed by IVB injection. IVD implantation was performed for all IVBtreatment-resistant cases. VA and CMT values were compared before and at three months after the first IVDimplantation. Results: The mean VA values before and at 3 months after the first IVD implantation were 0.69 ± 0.19 logarithmof the minimum angle of resolution (logMAR) (1.50 to 0.10 logMAR) and 0.26 ± 0.07 logMAR (1.00 to 0.00logMAR), respectively (p < 0.001). The mean CMT was 476.13 ± 135.13 mm (314 to 750 mm) and 294.06 ±15.26 mm (222 to 480 mm), respectively (p < 0.001). The mean number of implanted IVD was 1.44 ± 0.89 (1to 4) and the mean follow-up time was 7.4 ± 4.6 months (6 to 24 months). After IVD implantation therapy, themean VA and CMT values were 0.19 ± 0.05 logMAR (0.70 to 0.00 logMAR) and 268.38 ± 31.35 mm (217 to351 mm), respectively. Conclusions: To the best of our knowledge, this is the first report to show the efficacy of IVD implantationeven after repeated IVB injections in treatment-resistant PCME. IVD implantation is both a safe and effectivemethod for decreasing PCME after both uneventful and complicated cataract surgery.
