How does the Accommodating IOL work?
As we change our focus from distance to near, the natural human lens moves within the eye. That is why young people can see very fine print without glasses. This ability is lost with age and our range of vision diminishes, particularly at near, thus necessitating reading glasses.
The Crystalens is designed to slightly and imperceptibly move and flex in response to your natural focusing muscles inside the eye, allowing it to change power or accommodate, thus restoring some of this reading vision.
The two-year clinical trial that supported the FDA approval of the Crystalens indicated that 92% of the people enrolled in the study (implanted bilaterally) could see 20/25 or better at distance, 96% could see 20/20 at arm's length and 73% could see 20/25 at near without glasses or contact lenses.
What is more exciting is that 98% of these people could pass their driver’s test, 100% could see their computer and dashboard, read the prices in the supermarket or put on their makeup, and 98% could read the telephone book or newspaper, all without glasses or contact lenses.
Most patients achieve a large degree of spectacle-independence for distance and intermediate vision and only use glasses for reading.
