Lid flora in blepharitis.

The microbiologic evaluations of 332 consecutive patients with the primary diagnosis of chronic blepharitis were reviewed and compared to those of 160 control patients. The most commonly isolated organisms from lids with blepharitis were Staphylococcus epidermidis (95.8%), Propronibacterium acnes (92.

Continuous tear capsulotomy and phacoemulsification cataract extraction combined with penetrating keratoplasty.

Continuous tear capsulotomy, or capsulorhexis, permits secure and precise placement of a posterior chamber intraocular lens. This technique can be used open sky during triple procedures combining penetrating keratoplasty with cataract extraction and intraocular lens insertion. Expression of the nucleus through a continuous tear capsulotomy can be difficult.

Porcine collagen corneal shield treatment of persistent epithelial defects following penetrating keratoplasty.

Treatment of persistent epithelial defects following penetrating keratoplasty (PK) can be difficult. The use of a 24-hour porcine collagen corneal shield (Bausch & Lomb) to promote epithelialization of these cases was compared to the use of the hydrophilic bandage soft contact lens (Bausch & Lomb, plano O4). Twenty-three consecutive patients treated for persistent epithelial defect following PK were reviewed.
