Though Crystalens and Trulign Toric accommodating IOLs provide an expanded range of clear vision compared with conventional monofocal intraocular lenses, you may still need reading glasses to comfortably see small print and perform other near vision tasks.
The primary difference between a conventional monofocal IOL and an accommodating IOL is the design of these haptics.
In a conventional IOL, the haptics are designed to keep the optical portion of the implant stationary, with no rotation or anterior/posterior movement that could affect vision.
In an accommodating IOL, the haptics are designed to keep the IOL securely in place and prevent any rotational movement, but the legs are flexible in a way that allows the optical portion of the IOL to move slightly forward upon contraction of the ciliary muscle.
In this fashion, an accommodating IOL can expand the range of clear vision after cataract surgery, providing better near vision without eyeglasses than what is possible with a conventional monofocal IOL procedure.
Your cataract surgeon can help you decide if accommodating IOLs or multifocal IOLs are the right choice for your particular needs during your preoperative eye exam and consultation.
