Topical anesthesia for penetrating keratoplasty produced successful results in cooperative patients with perforated corneal ulcers, a study found.
The prospective, interventional case series included 17 eyes of 15 patients who underwent PK under topical anesthesia to treat corneal ulcers. Eight eyes were phakic, eight eyes were pseudophakic and one eye was aphakic.
The procedure was successful in all eyes.
Three eyes developed an anterior capsular tear; one eye underwent implantation of a posterior chamber IOL, and two eyes were identified as aphakic.
At the final visit, clear grafts were seen in 10 eyes and partly clear grafts were seen in seven eyes.
Ten eyes had best corrected visual acuity better than 6/18 while seven eyes had BCVA between 6/60 and 6/24.
Due to pain, anxiety and a longer surgery time, patients who undergo PK with topical anesthesia need extra verbal support and instruction compared with topical cataract patients, the study authors said.
