Posterior chamber phakic IOLs, particularly the Visian ICL™, are highly effective for correcting a wide range of refractive errors, including those who may not be suitable candidates for LASIK or other laser-based procedures. The central aquaport design in newer EVO ICL models significantly reduces the risk of complications such as ocular hypertension, anterior subcapsular cataract, and pigment dispersion by allowing the physiologic flow of aqueous humor. Intraoperative complications, including lens tearing, sticky or up-bent haptics, and incorrect lens orientation, are rare and can be managed with specific techniques. Postoperative visual disturbances, like glare and halos, are typically transient and resolve within 1 to 12 months. Long-term studies demonstrate minimal endothelial cell loss and excellent visual outcomes, with high patient satisfaction. The “Zaldivar ICLguru” method, utilizing a dual deep learning architecture, ensures precise lens sizing and adequate vaulting, which is crucial for maintaining the health of the eye. Specialized biometry techniques, such as high-frequency ultrasonography and anterior segment OCT, are essential for accurate preoperative evaluation.
