Prediction Accuracy of Total Keratometry Compared to Standard Keratometry Using Different Intraocular Lens Power Formulas.

Purpose: To compare the accuracy of intraocular lens (IOL) power calculation based on standard keratometry (K) and the new Total Keratometry (TK).

Methods: A post-hoc analysis of study data based on 145 pseudophakic astigmatic eyes was conducted. The absolute prediction error (APE) of spherical equivalent (SE) and cylinder (CYL) was calculated based on K and TK (including posterior corneal surface) data recorded 6 weeks after IOL implantation.

Troponin in Cardiovascular Disease Prevention: Updates and Future Direction.

Cardiac troponin has been well described as the preferred biomarker for diagnosis of myocardial infarction due to the high sensitivity and specificity for myocardial injury. Numerous other conditions apart from acute coronary syndrome can also lead to small elevations in troponin levels. However, the use of cTn as prognostic biomarker for the primary assessment of cardiovascular risk in asymptomatic patient has only recently been described.

Prevention of lens capsule opacification with ARC neodymium:YAG laser photolysis after phacoemulsification.

We describe a technique that uses a neodymium:YAG (Nd:YAG) laser photolysis system to prevent lens capsule opacification. The photolysis instrument consists of a 1064 nm Nd:YAG laser transmitted along a fiber-optic cable into a handpiece containing an angulated titanium plate that the laser beam strikes, creating plasma and a shockwave that exits the handpiece through an aperture. Under direct visualization, the shockwave is aimed at the inner surface of the anterior capsule, where it removes LECs and proteoglycan attachment molecules; the shockwave probably extends to the capsule fornix, destroying germinal epithelial cells.

[Microincision intraocular lens with plate haptic design. Evaluation of rotational stability and centering of a microincision intraocular lens with plate haptic design in 12-19 months of follow-up].

Background: Evaluation of rotational stability of a microincision intraocular lens with plate haptic design (*Acri. Smart 46S, *Acri.Tec AG) and its centering in the capsular bag after implantation.

[Phacoemulsification and vitrectomy with the erbium:YAG laser and phacoemulsification with the neodymium:YAG laser].

There are an increasing number of possible applications for the use of Erbium:YAG and Neodymium:YAG lasers in ophthalmology. Laser-phacoemulsification as well as Erbium-laser vitrectomy is of major interest. We report on the underlying technology and more than 1-year-experience using the PHACOLASE (Asclepion-Meditec, Jena, Germany, 10-100 Hz frequency, 5-50 mJ single pulse energy) for phacoemulsification and pars plana vitrectomy and the Lyla-Dodick laser photolysis (A.
