Penetrating keratoplasty (PKP) triple procedures with a 25G system is a safe and effective treatment option.
Penetrating keratoplasty (PKP) triple procedures with a 25G system is a safe and effective treatment option, claims a study in the journal Cornea.
Dr Shiro Higaki et al., Department of Ophthalmology, Kinki University Faculty of Medicine, Osaka-Sayama, Japan, divided 30 patients into three groups. The groups were 12 eyes of 12 patients in the PKP group that underwent 25G vitrectomy, 9 eyes and 9 patients that underwent 20G vitrectomy and 9 eyes of 9 patients in the non-core vitrectomy group who underwent PKP without core vitrectomy.
The success rates of the IOL implantation were 97.1%, 88.9% and 66.7% for the 25G, 20G, and non-core vitrectomy groups, respectively. At 69 minutes for an average operation time the 25G group demonstrated the shortest time, compared to 82 minutes, and 90 minutes in the 20G group and the non-core vitrectomy group, respectively.
The PKP triple procedure with the 25G system offers a higher success rate of IOL implantation and significantly reduced operation time compared to 20G and non-core vitrectomy.
