- Can experience haloes or slight glare around lights at night, as a result of light being seen by the near and distance focusing zones of the lens implants. The brain usually learns to ignore these haloes and they become less noticeable over time
- Can take weeks or months to adapt to vision
- Glasses may still be needed for some tasks such as prolonged reading
- Very small text or reading in low light environment
- Share same major risk factors as cataract surgery (less than 1%)
- Patients need good light to improve reading vision
- Laser enhancement, such as YAG laser capsulotomy, may be advised in some patients
However, several factors may lead to a person requiring additional help from glasses or contact lenses after the surgery. Though very precise measurements and surgical technique are used for RLE surgery, healing response in each patient may result in some variability of final refractive outcome. Generally, this variability is very small, and people are highly satisfied with the surgery. LASIK or PRK may sometimes be used after RLE to “touch up” any residual refractive error. Occasionally, glasses or contact lenses are still needed for improved vision in certain viewing situations following RLE surgery.
