ICL Surgery Lens Options
Implantable Collamer Lenses come in different designs to correct myopia, hyperopia and astigmatism, with options tailored to your refractive error, age and visual priorities. Blue Fin Vision® offers monofocal, toric and monovision options, with pros, cons and suitability matched to your lifestyle and vision goals.
What are Implantable Collamer Lenses?
ICLs are precision medical devices implanted behind your iris to correct refractive error permanently. They come in different designs to correct distance vision (myopia and hyperopia), astigmatism, and in select cases, presbyopia. Choice depends on your refractive error, age, eye health, visual goals and lifestyle. Monofocal ICLs are standard and excellent for distance vision; toric ICLs correct astigmatism; monovision ICLs address presbyopia in patients aged 45–50.
Your chosen ICL will remain in your eye for life, making careful selection essential to match your refractive error and visual priorities. The lens is removable and reversible, offering flexibility if your vision needs change in future.
Monofocal ICL
Monofocal ICLs provide sharp distance vision to correct myopia (short-sightedness) or hyperopia (long-sightedness), optimising clarity for driving, outdoor activities and distance-focused tasks.
Advantages:
- Sharp, predictable distance vision with excellent optical quality
- Minimal glare or halos; excellent night vision performance
- Ideal for younger patients (21–45) prioritising distance clarity
- Fastest adaptation, with clear distance vision immediate after treatment
- No adaptation period; stable vision from Day 1
- Suitable for most eye types and refractive errors
Disadvantages:
- Reading glasses required for near tasks (reading, mobile phones, detailed work)
- Intermediate vision (computer work) may benefit from glasses
- Less versatile for patients over 45 seeking near vision clarity
- For patients over 50, presbyopia (age-related near vision loss) means reading glasses become necessary
Ideal for patients:
- Aged 21–45 with stable refractive error and healthy eyes
- Prioritising sharp distance vision and clear driving ability
- Active lifestyle requiring excellent distance clarity (sports, outdoor activities)
- Accepting reading glasses for near work
- Working in distance-focused roles (pilots, surveyors, outdoor professionals)
- With budget considerations or specific eye conditions requiring monofocal lenses
Toric ICL (for Astigmatism)
Toric ICLs correct astigmatism (irregular corneal curvature) up to 6.0 diopters, either alone or combined with myopia or hyperopia correction. These lenses require precise alignment and sizing to prevent rotation and ensure optimal astigmatism correction.
Advantages:
- Eliminates or significantly reduces astigmatism without glasses or contact lenses
- Precise correction delivering sharp, clear vision across visual field
- Ideal for patients with high astigmatism previously unsuitable for laser eye surgery
- No reliance on contact lenses or glasses for astigmatism management
- Excellent optical quality for everyday activities
Disadvantages:
- Requires accurate measurement and alignment; precise lens positioning is critical
- Potential for minor rotation (though modern lenses have excellent stability)
- Slightly more complex surgical planning than standard monofocal ICLs
- Rotation of more than 10 degrees can reduce astigmatism correction effectiveness
- Annual vault measurements essential to confirm lens stability
Ideal for patients:
- With astigmatism up to 6.0 diopters (myopic or hyperopic astigmatism)
- Aged 21–45 with stable refractive error including astigmatism
- Prioritising clear distance vision without glasses or contacts
- Active lifestyle requiring reliable distance clarity
- Previously unsuitable for LASIK or PRK due to astigmatism or corneal concerns
- Willing to attend annual follow-ups to confirm lens stability
Monofocal ICL with Monovision (for Presbyopia)
For patients aged 45–50 with myopia and presbyopia (age-related near vision loss), monofocal ICL with monovision targeting can provide functional near and distance vision without reading glasses. One eye is targeted for distance, the other for near vision, requiring brain adaptation.
Advantages:
- Functional near and distance vision without glasses for many daily tasks
- Eliminates reliance on reading glasses for many activities
- Delivers both myopia and presbyopia correction in one solution
- No additional surgery; standard ICL procedure
- Effective for motivated patients willing to adapt
Disadvantages:
- Requires brain adaptation; may take weeks to achieve comfortable binocular vision
- Potential for slight reduction in overall sharpness (each eye sees one distance well)
- Not suitable for patients who cannot adapt to monovision
- May reduce contrast sensitivity or depth perception slightly
- Some patients still prefer glasses for certain tasks (detailed reading, precision work)
- Requires careful patient selection and realistic expectations
Ideal for patients:
- Aged 45–50 with myopia and presbyopia
- Motivated to avoid reading glasses and willing to adapt to monovision
- Suitable eye anatomy confirmed during comprehensive assessment
- Healthy eyes with good retinal function
- Willing to undergo trial contact lens monovision first to test adaptation
- Accepting that some fine detail work may still require glasses

|---|---|---|---|
Distance vision | Excellent | Excellent | Excellent (one eye) |
Astigmatism correction | None | Up to 6.0D | None |
Near vision (reading) | Glasses needed | Glasses needed | Functional (one eye) |
Overall spectacle independence | Low | Low–Moderate | Moderate |
Glare/halos | Minimal | Minimal | Minimal |
Night vision quality | Excellent | Excellent | Excellent |
Adaptation period | Immediate | Immediate | Weeks to months |
Best for | Distance clarity | Astigmatism + distance | Near and distance balance |
Age suitability | 21–45+ | 21–45+ | 45–50 |

Toric ICL Alignment and Stability
If you have astigmatism, precise corneal mapping during pre-operative assessment ensures optimal toric lens alignment. Toric ICLs are designed with excellent rotational stability, and significant rotation is uncommon with modern lens designs. Your annual vault measurements will include rotation assessment to confirm your toric lens remains properly aligned for optimal astigmatism correction.
Factors in Choosing Your ICL
Selection during consultation considers:
Refractive Error
- Myopia (short-sightedness): Standard monofocal or toric ICL
- Hyperopia (long-sightedness): Standard monofocal or toric ICL
- Astigmatism: Toric ICL for precise correction
- Combined myopia/hyperopia + astigmatism: Toric ICL
- Myopia + presbyopia (age 45–50): Monovision ICL consideration
Age and Life Stage
- Under 45: Monofocal or toric; monovision not suitable
- 45–50: Monovision ICL option if suitable; standard monofocal or toric also available
- Over 50: Standard monofocal or toric recommended; consider lens replacement (refractive lens exchange) for presbyopia
Lifestyle and Visual Priorities
- Distance-focused work or hobbies: Monofocal or toric ICL
- Sports and outdoor activities: Monofocal or toric for sharp distance vision
- Reading-dependent work (under 45): Standard monofocal; accept reading glasses
- Balanced distance and near (45–50): Monovision ICL consideration
Eye Health
- Healthy eyes: All options available
- Thin corneas: ICL ideal (vs. LASIK unsuitable)
- High myopia (above -10D): ICL often better than LASIK
- Dry eye predisposition: ICL better choice than LASIK
- Previous corneal surgery (LASIK, PRK): ICL excellent alternative with specialist planning
Budget Considerations
- Standard monofocal ICL: Cost-effective, excellent distance vision
- Toric ICL: Premium for astigmatism correction; worth investment if astigmatism significant
- Monovision ICL: Similar cost to monofocal; consideration depends on age suitability and adaptation willingness
- Remember: ICL cost is one-time investment for life-long vision improvement, and the lens is removable if needs change.
Realistic Expectations
- No ICL guarantees 100% glasses freedom for all tasks
- Monofocal ICLs require reading glasses for near work (expected and manageable)
- Toric ICLs eliminate astigmatism but still require reading glasses for near work if patient is myopic
- Monovision ICLs offer functional near and distance but require brain adaptation and may reduce overall sharpness slightly
- Your visual priorities and acceptance of trade-offs guide optimal choice
- Most patients report excellent satisfaction with distance vision and quality of life improvement
