Purpose
This study aimed to investigate the changes in postoperative ocular biometric parameters in end-stage renal disease patients who underwent renal transplantation.
Material and methods
This retrospective study included a total of 33 eyes of 33 patients. The ocular biometric measurements which were evaluated were axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), corneal keratometry (K1 and K2), degree of astigmatism, lens thickness (LT), and intraocular pressure (IOP). Refractive prediction error (RE) was calculated before and after renal transplantation using the same diopter (D) for intraocular lens (IOL) power calculation and evaluated for potential cataract surgery.
Results
The study included 15 male (45%) and 18 female (55%) patients. Mean patient age was 31.55 ± 8.24 (range: 18–49 years). In the comparison of preoperative and 1-month postoperative measurements, there was a statistically significant difference in AL, LT, ACD, and CCT (p < 0.001). There was no statistically significant difference between K1, K2, and astigmatism measurements (p = 0.72; p = 0.35; p = 0.62, respectively). There was no statistically significant difference in RE (p = 0.61-Holladay 2).
Conclusion
While renal transplantation surgery does not lead to significant changes in astigmatism, predicted refractive error, corneal keratometry, or intraocular pressure, it causes significant decrease in axial length, lens thickness, and central corneal thickness and significant increase in anterior chamber depth. However, these changes do not result in significant changes in IOL power calculation in planned cataract surgery.
