AT LISA trifocal intraocular lenses are premium lenses implanted during cataract or clear lens surgery. They aim to give clearer distance, intermediate, and near vision with less need for glasses.
How AT LISA lenses help
These lenses replace the natural lens inside the eye. Their trifocal optics distribute light for several focusing distances so you can manage more tasks without spectacles.
- Distance focus supports activities like driving and outdoor sports.
- Intermediate focus helps with computer use, cooking, and hobbies.
- Near focus assists with phones, reading, and fine detail work.
- The lens stays in place permanently and does not require cleaning.
- Careful measurements before surgery guide lens power choice.
Benefits and possible side effects
Many patients enjoy greater independence from glasses after surgery. However, some experience haloes, glare, or reduced contrast in dim light, particularly early on.
- Good tear film and healthy corneas support crisp vision.
- Neuroadaptation, where the brain adjusts, usually improves visual comfort over months.
- Night driving may feel unusual at first and might need extra care.
- Not everyone is suitable, especially with significant macular or corneal disease.
- Thorough counselling and realistic expectations are essential before choosing this lens.
