Understanding Intraocular Lenses (IOLs) at ReFocus Eye Health North Wales

Monofocal lenses provide clear vision at one set distance, usually for driving or seeing far away. Glasses may still be needed for reading or close work, but these lenses offer excellent reliability and visual clarity.

• Ideal for patients comfortable using reading glasses.
• Good contrast and minimal night glare.
• Usually covered by insurance for cataract surgery.

Multifocal IOLs have special zones to focus at near, intermediate, and distance ranges. Many people enjoy reduced dependence on glasses for both reading and seeing at a distance.

• Designed for active lifestyles and frequent use of digital screens.
• Some patients may notice halos, especially in the early weeks.
• Requires a brief adjustment period as your brain adapts.

EDOF lenses offer a continuous range of focus, making it easier to switch between seeing far away, computer work, and arm’s-length tasks without much blur.

• Less likely to produce halos or glare than multifocals.
• Great for patients who spend a lot of time on screens or in varied lighting.
• Helps reduce the need for glasses in daily routines.

Toric IOLs are designed to correct the uneven curve of the cornea found in astigmatism, providing sharper, more undistorted vision after surgery.

• Helps decrease the need for additional vision correction.
• Available in both monofocal and advanced models.
• Requires precise alignment during surgery for best results.

Light-adjustable lenses can be fine-tuned after surgery using a special light treatment. This innovative option lets your eye doctor personalize vision correction once your eye has healed.

• Ideal if your vision goals are uncertain or change over time.
• Allows for non-surgical adjustments post-op.
• Provides a truly custom fit for your vision needs.

Accommodating lenses gently shift in response to your eye muscles, helping with both near and distance tasks. Results vary, and some reading glasses may still be needed for small print.

• Designed to move and focus naturally as your eyes adjust.
• Great for activities like crafts, cooking, and hobbies.
• May be combined with other lens options for specific needs.

The need for glasses after surgery depends on your IOL type. Many patients with multifocal or EDOF lenses need them less often, while those with monofocal lenses often use reading glasses for close tasks. Your results will be unique based on your lens and eye health.

Today’s FDA-approved IOLs are made to last for decades. Most patients enjoy excellent outcomes, but some eye conditions (like glaucoma or retinal disease) may affect lens choice and long-term vision results. Regular eye exams are important to keep your eyes healthy after surgery.

• Complications are rare and most side effects improve with time or simple treatments.
• Your doctor will discuss all risks and safety information prior to surgery.
