Purpose
To evaluate the accuracy of intraocular lens (IOL) power calculation formulas, refractive outcomes, and postoperative complications following lensectomy in simple extreme microphthalmos cases.
Setting
University of Health Sciences, Beyoğlu Eye Training and Research Hospital
Methods
This retrospective study analyzed patients with extreme microphthalmos (axial length <18 mm) who underwent lensectomy between January 2015 and July 2024. Data collection included demographic details, preoperative and postoperative best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of antiglaucomatous medications, anterior chamber depth (ACD), IOL power calculation formulas (Hoffer Q and SRK-T), the diopter of implanted intraocular lens (IOL), the final refractive error and surgical complications.
Results
The study included 27 eyes of 16 patients.Mean axial length was16.59±0.84 mm.Mean preoperative spherical refractive error was +11.72±3.76 D.IOL was chosen according to SRK-T formula in 6(22.22%) and Hoffer-Q formula in 21(77.78%) eyes.Mean IOL power was 50.79±6.78 D.Postoperatively,significant improvement was observed in BCVA(p<0.05),IOP(p=0.02),ACD(p=0.06),antiglaucomatous medication(p=0.02).There was significant difference between aimed refractive error and postoperative refractive error (p=0.03).Postoperative myopic error was observed in 1(16.7%) eye in SRK-T group and 15(71.4%) eyes in Hoffer-Q group.Surgical complications included choroidal effusion(11.1%),malignant glaucoma(7.41%).Posterior capsule rupture occurred in 4(14.81%) eyes.
Conclusions
Lensectomy in extreme microphthalmos cases reduces IOP and the number of antiglaucomatous medications while improving BCVA. However, IOL power calculations remain inconsistent. Further studies are needed to refine formula accuracy and optimize surgical outcomes in this complex patient population.
