Methods: This retrospective study included patients who underwent cataract surgery at the Çanakkale Onsekiz Mart University Ophthalmology Clinic between 2020 and 2025. Patient demographics and ophthalmologic examination findings were recorded. Autorefractometry data obtained at the first postoperative month, preoperative anterior chamber depth (ACD), axial length (AL), postoperative keratometry values, and dioptric power of the implanted IOL (IOL-D) were included in the study. Postoperative LA values were calculated using two different artificial intelligence programs using the Jaffe vector analysis method. Factors affecting LA were investigated using one-way linear regression analysis (LRA).

Results: A total of 58 patients were included in the study: 29 patients implanted with an HPo acrylic monoblock foldable IOL (Group 1) and 29 patients implanted with an HPi acrylic IOL (Group 2). No statistically significant differences were found between the groups in terms of age, gender, AL, ACD, IOL-D, keratometry, and LA (p > 0.05). LRA in Group 1 found that the preoperative ACD was significantly associated with the LA, and this variable explained 19.1% of the LA variance (p = 0.02; 95% CI: 0.051?0.683).

Conclusions: In the HPo IOL group, a significant and positive correlation was found between preoperative ACD and LA. Therefore, it is recommended that preoperative ACD be taken into account to optimize refractive outcomes in patients planned for HPo acrylic IOL implantation.
