Does Every Calculation Formula Fit for All Types of Intraocular Lenses? Optimization of Constants for Tecnis ZA9003 and ZCB00 Is Necessary.

: To evaluate the performance of intraocular lenses (IOLs) using power calculation formulas on different types of IOL. : 120 eyes and four IOL types (BioLine Yellow Accurate Aspheric IOL (i-Medical), TECNIS ZCB00, TECNIS ZA9003 (Johnson & Johnson) (3-piece IOL) and Softec HD (Lenstec)) were analyzed. The performance of Haigis, Barret Universal II and SKR-II formulas were compared between IOL types.

Periocular basal cell carcinoma - clinical perspectives.

Basal cell carcinoma (BCC) as a non-melanoma skin cancer type is the most common malignant tumor throughout the world. The incidence is higher in age over 60. The intense of exposure to ultraviolet radiation is one of the known risk factors.

Subtotal Exenteration of the Orbit for Benign Orbital Disease.

Purpose: Total exenteration of the orbit with removal of the eye globe and surrounding tissues is most frequently indicated for malignant tumors. The indications for exenteration of the orbit for benign orbital lesion are rare. Not adequately treated infection of the orbit by systemic antibiotics can lead to destructive changes of soft tissues in the region of the orbit and partial exenteration with eyelid sparing technique is necessary.
