Abstract:
The authors developed a new surgical technique of retropupillary implantation of an iris-claw intraocular lens (RP-ICIOL). RP-ICIOL is an alternative surgical option to the scleral-fixation technique for the treatment of aphakia without capsular support. Several studies have shown that RP-ICIOL is efficient and safe. However, although it is easier to perform than scleral fixation, it presents some critical issues related to the enclavation procedure. The success of the correct enclavation without excessive surgical manipulations, with subsequent pigment dispersion and without pupil distortion, is highly related to the surgical skills of the individual surgeon. The new technique proposed by the authors consists of using a guide needle to facilitate the enclavation, and to make this surgical procedure standard. The new technique was performed in 26 patients affected by aphakia without capsular support with encouraging functional and anatomical results.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Steel Fastening Techniques
Rivets are cylindrical steel fasteners with a specially designed head. During application, rivets are heated until white-hot and then inserted through pre-drilled holes in the steel sections. A pneumatic hammer is used to shape the exposed end into a second head, securing the sections together.
