Abstract Objective To investigate the effect of mydriasis on ocular parameters measured by optical biometrics and intraocular lens power calculation. Methods A total of 27 cataract patients admitted to Jingde Eye Hospital of Texas from December 13 to 19, 2021 were selected as the research objects. Optical biometry was performed without mydriasis and mydriasis, axial length (AL), anterior chamber depth (ACD) and anterior corneal surface curvature were recorded.The posterior chamber intraocular lens (IOL) degrees before and after mydriasis were calculated by SRK/T and Haigis formulas respectively. Results The ACD before mydriasis was lower than that after mydriasis, the difference was statistically significant (P＜0.05). There was no significant difference in AL before and after mydriasis (P>0.05). There was no significant difference in flat K (FK) and steep K (SK) between pre-and post-mydriasis (P>0.05). There was no significant difference in IOL values calculated by SRK/T formula and Haigis formula between pre-and post-mydriasis (P>0.05). Conclusion Drug-induced mydriasis has no significant effect on the diopter value of posterior chamber IOL calculated by SRK/T formula and Haigis formula, but it significantly affects the intraocular ACD value measured by optical biometric method.

Key words： Mydriasis Optical biometry Intraocular lens calculation SRK/T formula Haigis formula Axial length;Anterior chamber depth
