Abstract:
Objective To evaluate the operative outcomes of a triple procedure including simultaneous penetration keratoplasty (PKP),extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation,and to investigate the relationship between postoperative corneal refractive power and preoperative lens diopter.Methods This retrospective analysis study involved 15 patients who had undergone a triple procedure surgery in Beijing You'an hospital from April to October 2016.Outcomes including the best corrected visual acuity (BCVA),intraocular pressure (IOP),corneal refractive power,axial length,postoperative complications,corneal endothelial cell counts and the survival of corneal graft were determined one year after surgery.Results All corneal grafts were transparent and corneal endothelium were (1974.20 ±472.82) cell · mm-2.The mean postoperative LogMAR visual acuity (0.80 ±0.27) had a significant improvement compared with the mean preoperative LogMAR visual acuity (2.63 ±0.62) (t =13.042,P ＜0.001).There were no statistically significant differences in preoperative IOP (15.27 ± 2.37) mmHg (1 kPa =7.5 mmHg) and postoperative data (14.53 ± 3.04) mmHg (t =0.685,P =0.505),preoperative axial length (23.69 ±2.01) mm and postoperative data (23.62 ±2.12)mm (t =-0.138,P=0.893)and preoperative keratometry (45.01 ± 1.66) D of the control eye and postoperative data (42.56 ± 5.48) D (t =1.202,P =0.260).The postoperative spherical equivalent refractive was (0.40 ±4.65) D,and the target refraction was (0.58 ±0.25)D.Conclusion The triple procedures are safe and effective for the treatment of patients with coexisting corneal pathologies and cataracts.Selection of emmetropia lens diopter may result in the satisfactory postoperative visual acuity.However,unpredictable postoperative corneal curvature changes will still affect the final refractive state.
