[Post operation complications analysis and their treatment of Descemet's stripping automated endothelium keratoplasty].

OBJECTIVE

To summarize intra and post operation complications and their treatment of Descemet's Stripping Automated Endothelium Keratoplasty (DSAEK), and provide our experience for its development in China.

METHODS

Retrospective case study. Forty-seven eyes of 42 patients underwent DSAEK performed by one surgeon. Indications include: Pseudophakic or aphakic Bullous Keratopathy, 27 eyes (57.4%); Fuchs Endothelial Dystrophy, 7 eyes (14.9%); endothelial decompensation post vitrectomy, 3 eyes (6.4%); iridocorneal endothelial syndrome (ICE), 3 eyes (6.4%); congenital glaucoma, 3 eyes (6.4%); graft failure post endothelial keratoplasty, 3 eyes (6.4%); endothelial decompensation after open ocular injury and intraocular foreign body, 1 eye (2.1%). Nineteen eyes underwent single DSAEK (40.4%); eight combined phacoemulsification and intraocular lens implantation (17.0%); eight combined anterior chamber IOL (AC-IOL) removal plus anterior segment vitrectomy and posterior chamber IOL (PC-IOL) implantation (17.0%); eight combined anterior segment vitrectomy and PC-IOL suspension (17.0%); two combined cataract extraction and anterior segment vitrectomy (4.3%); two failed in DSAEK and underwent penetrating keratoplasty (4.3%).

RESULTS

Dislocation is the most common postoperative complications. Ten eyes underwent dislocation in 47 eyes (21.3%), which was solved by air and viscoelastic agent injection. High intraocular pressure happened in 12 eyes (25.5%), in 11 of which had a history of glaucoma and 1 with ICE. After drug treatment, ten patients had stable intraocular pressure and two patients underwent ciliary body photocoagulation surgery (1 case with anterior chamber intraocular lens, 1 case with ICE). Reactions happened in 2 cases (4.3%) patients, including 1 case with anterior chamber IOL (AC-IOL) rehabilitating after drug treatment and the other with Fuch's corneal endothelial dysfunction being regrafted.

CONCLUSION

Dislocation is the most common complication after corneal endothelial keratoplasty, and air injection in anterior chamber is a common and effective method; High intraocular pressure is the second postoperative complication. Preoperative history of glaucoma is closely related to postoperative high intraocular pressure.
