Watertight Ray/Triangle Intersection

We propose a novel algorithm for ray/triangle intersection tests that, unlike most other such algorithms, is watertight at both edges and vertices for adjoining triangles, while also maintaining the same performance as simpler algorithms that are not watertight. Our algorithm is straightforward to implement, and is, in particular, robust for all triangle configurations including extreme cases, ...

Cataract Surgery Creating a Watertight Incision

MAY 2010 CATARACT & REFRACTIVE SURGERY TODAY 35 David R. Hardten, MD For lens implantation, especially with the newest presbyopia-correcting IOLs, all aspects of the cataract surgical procedure should be of the highest quality to achieve the goal of rapid visual recovery. Safety must also be a high priority, as surgeons try to perfect all of the procedure’s steps to meet patients’ ever-rising e...

Corneal trephining for penetrating keratoplasty.

MANY complications following corneal grafting procedures may be attributed to the technical and biological problems associated with this type of surgery. It is generally agreed that accurate apposition of the graft to the margin of the incision in the recipient cornea is of the greatest importance. Manual trephining for penetrating keratoplasty frequently results in badly cut grafts, and for th...
