Multifocal versus accommodating intraocular lenses: a review of the current technology, outcomes, and complications

Clinical application of accommodating intraocular lens

The present review describes recent advances in application of accommodating intraocular lenses (AIOLs). Standard monofocal intraocular lenses (MIOLs) only correct distance vision, while AIOLs are designed to allow both good distance vision and near vision, which is achieved through the contraction and relaxation of ciliary muscles by providing transformation of the axial movement or curvature of the lens. Thus, AIOLs may be a better choice for those patients who demand a higher level of visual performance. Since techniques to analyze the performance of AIOLs have not been standardized, and there is a variety of both subjective and objective methods, it is hard to measure the performance of these intraocular lenses. By evaluating advantages and disadvantages of various AIOLs, and introducing techniques for measurement the performance postoperative, this paper can provide some relative information on choosing the type of AIOLs in the clinic.

Risk of Breaking Haptic of Trifocal IOL and Its Management

Fracture of an intraocular lens (IOL) haptic is a rare complication of cataract surgery. A broken haptic can cause serious damage in the anterior and posterior segments. To the best of our knowledge, a broken haptic in a high-quality, commercially available trifocal IOL has not been documented in the literature. Prompt and proactive action at 1 day postoperatively aided in addressing the complication and restoring the vision. We suggest that the ophthalmologist performed a thorough evaluation on the 1^st postoperative day and take immediate action after a discussion with the patient and relatives.
