The results suggest that Opegan is more effective than Healon in protecting corneal endothelial cells during phacoemulsification regardless of the amount of ultrasound energy used.

Treatment for 12 months with BAK-free travoprost after BAK-preserved latanoprost resulted in fewer ocular surface complications, as indicated by the reduced prevalence of SPK and decreased hyperemia, and no clinically relevant changes in IOP. BAK-free travoprost may have beneficial effects on the ocular surface while showing IOP-lowering efficacy comparable with BAK-preserved eye drops.

The surface scattering of MA60BM and SA60AT is higher than that of AR40 and ClariFlex. The grades of surface scattering differ among the manufacturers, even with the same acrylic material.

Surface light scattering with the implanted foldable hydrophobic acrylic IOL continuously increased during the postoperative years and was a risk for decreased visual acuity.

. Purpose:  To examine improvement with the use of Scheimpflug imaging of the anterior and posterior corneal surfaces in the accuracy of ray‐tracing intraocular lens (IOL) power calculation for normal cataractous eyes. Methods:  Prospective case series comprised 136 eyes of 136 consecutive patients who had undergone cataract surgeries. Scheimpflug imaging of the cornea was included with routine preoperative examinations. Postoperative refractions were predicted using three methodologies; ray‐tracing calculation using Scheimpflug imaging and Placido topography, ray‐tracing calculations using Placido topography, and the SRK/T formula using autokeratometry. Prediction errors from the manifest refraction at 1 month postoperatively were compared between the methods. Influence of the posterior corneal curvature was also evaluated. Results:  Mean prediction errors were 0.008, −0.103 and −0.042 D, respectively without significant difference between the three methods (p = 0.23). The prediction errors were significantly correlated with the posterior corneal curvature when the Scheimpflug imaging was not used (p < 0.03). Conclusion:  Use of Scheimpflug imaging in ray‐tracing IOL power calculation was as accurate as the other calculations in normal cases, showing no bias in the posterior corneal curvature, as is the case with the other calculations.
