Clinically significant intraocular lens decentration and til
A Study was conducted to investigate the occurrence and risk factors of clinically significant intraocular lens (IOL) decentration and tilt in highly myopic eyes using swept-source anterior segment optical coherence tomography (SS-AS-OCT).

This study included 334 participants with high myopia who underwent phacoemulsification with IOL implantation. Decentration and tilt of IOL were assessed by SS-AS-OCT. Clinically significant IOL decentration and tilt was defined as decentration more than 0.4mm and tilt more than 7°. Routine pre- and post-operative examinations were performed, including visual acuity, refraction, biometric measurement using IOL master 700, and objective visual quality evaluated by OPD-Scan III.

Results:
--Among the 334 highly myopic participants, 71 had clinically significant IOL decentration and 26 had clinically significant IOL tilt.

--The proportion of clinically significant IOL decentration (37.1% vs 14.0%) and tilt (16.2% vs 3.90%) in those with AL more than 30mm was significantly higher than those of AL less than 30 mm.

--In multivariable logistic regression model, only AL mo 30 mm was associated with clinically significant IOL decentration. AL more than 30mm was independent risk factors for clinically significant IOL tilt after adjusting for confounders.

Conclusively, participants with AL longer than 30mm have higher risk of clinically significant IOL decentration and tilt, thus cautious should be taken to implant multifocal or toric IOL for these patients.
