To describe the clinical outcomes of Descemet membrane endothelial keratoplasty combined with phacoemulsification/posterior chamber intraocular lens implantation (triple procedure) for treatment of corneal decompensation induced by a phakic anterior chamber intraocular lens (AC IOL) implantation.
Methods
Ten patients (10 eyes) with corneal decompensation due to phakic AC IOL implantation that had undergone the triple procedure were included in this study. Among the 10 eyes, 5 eyes underwent explantation of AC IOL prior to the transplantation, and then underwent the triple procedure. The remaining 5 eyes with a phakic AC IOL in situ underwent the triple procedure with concurrent explantation of AC IOL. Corrected distance visual acuity (CDVA), subjective refraction, endothelial cell density (ECD), and complications were documented.
Results
The triple procedure was performed across all eyes without any adverse events. The average CDVA improved from 1.32 ± 0.24 preoperatively to 0.15 ± 0.05 logarithm of the minimum angle of resolution (logMAR), which represents an improvement in Snellen equivalent from 20/400 (0.05) preoperatively to 20/28 (0.71) at 12 months after surgery. At 12 months, all eyes reached a CDVA of 20/32 (0.63) or better, and 50% of eyes reached a CDVA of 20/25 (0.8) or better. The mean donor ECD±SD was 2868.7 ± 67.9 cells/mm2, which decreased to 1724.1 ± 84.6 cells/mm2 at 12 months, representing 39.9% of endothelial cell loss. Patients did not experience any severe adverse events.
Conclusion
The triple procedure is a safe and effective option for corneal decompensation induced by a phakic AC IOL implantation, helping achieve a satisfactory visual rehabilitation with few complications.
