Influence of Ocular Biometric Parameters on Intraocular Lens Position: A Prospective Cohort Study.
Purpose: To assess the influence of ocular biometric parameters on intraocular lens (IOL) tilt and decentration after cataract surgery.
Methods: Patients scheduled for cataract surgery were screened for inclusion in this prospective cohort study. Tilt and decentration of the crystalline lens and IOL were measured using the CASIA2 (Tomey). Anterior chamber depth (ACD), lens thickness (LT), and axial length (AL) were preoperatively measured by the IOLMaster 700 (Carl Zeiss Meditec AG). Multivariate regression analysis was performed to assess the influence of ocular biometric parameters on IOL tilt and decentration after cataract surgery.
Results: In total, 191 eyes of 120 patients were included. Age was positively correlated with IOL tilt, whereas ACD and AL were negatively correlated with IOL tilt. A strong positive correlation was found between preoperative crystalline lenses and postoperative IOLs in tilt magnitude (r = 0.769, P < .001) and tilt direction (r = 0.688, P < .001). A positive correlation was found between preoperative and postoperative lens decentration magnitude and decentration direction. Greater postoperative IOL tilt and decentration were significantly associated with greater preoperative crystalline lens tilt (P < .001) and decentration (P = .027).
Conclusions: IOL tilt was greater in older patients. Shorter AL and shallower ACD contributed to greater IOL tilt. The tilt and decentration of the IOL will be greater in patients with greater tilt and decentration of the crystalline lens. [J Refract Surg. 2024;40(7):e438-e444.].
期刊介绍：
The Journal of Refractive Surgery, the official journal of the International Society of Refractive Surgery, a partner of the American Academy of Ophthalmology, has been a monthly peer-reviewed forum for original research, review, and evaluation of refractive and lens-based surgical procedures for more than 30 years. Practical, clinically valuable articles provide readers with the most up-to-date information regarding advances in the field of refractive surgery. Begin to explore the Journal and all of its great benefits such as:
• Columns including “Translational Science,” “Surgical Techniques,” and “Biomechanics”
• Supplemental videos and materials available for many articles
• Access to current articles, as well as several years of archived content
• Articles posted online just 2 months after acceptance.
