"Capsulocopsis": a new surgical instrument and method for capsulotomies.

Capsulotomy using a cystotome and continuous tear capsulorhexis has dramatically improved the quality of modern cataract surgery. The authors have devised a microscalpel that has a semicircular configuration and can turn 360 degrees and score or cut the anterior capsule. The blade also has the ability to salvage a radial tear that may occur during capsulorhexis by cutting the extension from the opposite direction and continuing the "peeling off" of the capsule.

Do human tears absorb ultraviolet light?

We analyzed human tears by ultraviolet (UV) spectrophotometry for transmittance of UV light. Ultraviolet light was readily transmitted through human tears in the UV-A (320-400 nm) and UV-B (290-320 nm) ranges. Tears partially absorbed UV light in the UV-C (100-290 nm) range. The clinical implications of these findings include prevention of phototoxic ocular damage and effects upon excimer laser corneal photoablative techniques.
