The IOLMaster 500, the latest generation of optical biometry from Carl Zeiss Meditec AG (Jena, Germany), offers surgeons a fast and easy way to calculate IOL power for their patients. According to company literature, this device is a complete workstation designed to meet the needs of a modern cataract practice. In the new dualmeasurement mode, multiple axial length and keratometry readings are captured automatically. The device's redesigned graphical user interface yields more data with fewer clicks than the previous generation. The optional Sonolink ultrasound connection provides optimal workflow even for those cases in which an optical axial length reading is not possible. The IOLMaster 500 software offers a range of recognized formulas for automatically calculating the targeted IOL power. With the IOLMaster 500, users can refine and personalize lens constants optimized for the IOLMaster found on the Users' Group for Interference Biometry (www.augenklinik.uni-wuerzburg.de/ulib/index.htm) Web site.

The Macaluso Pull-Through System (Oasis Medical, Inc., Glendora, California) is designed for endothelial graft insertion in posterior lamellar corneal transplantation procedures. According to the company, this system does not require an ophthalmic viscosurgical device (OVD), eliminating interface issues caused by OVD between the graft and host tissue. The loading platform is designed to eliminate the chance of tissue folding onto itself during inserter loading. The closed design of the inserter reduces the chance of chamber collapse, allows faster and more precise positioning of the graft, and keeps fluid from rushing over the graft and damaging endothelial cells. Additionally, the titanium inserting device with a lateral winglet allows the endothelial lenticle to be grasped by the loading and positioning forceps. The rubber-tipped plunger creates a seal that stabilizes pressure in the anterior chamber to avoid collapse.
