01
Assessing Cataract Severity
Examination of the natural lens to determine the degree of opacity and its effect on vision, glare, and daily activities.
Clinic Services
Cataract Surgery
Detailed cataract assessment using advanced diagnostic technology, with discussion of available options and selection of the most appropriate intraocular lens according to each patient’s measurements and daily visual needs.
Assessment & Treatment Journey
A Personalized Plan for Each Eye
The choice of surgery and lens is not the same for everyone; it depends on detailed testing, lifestyle, and individual visual needs.
02
Corneal Assessment
Assessment of corneal shape, thickness, and regularity to support accurate measurements and treatment planning.
03
Retina & Optic Nerve Assessment
Confirming retinal and optic nerve health and identifying factors that may affect the expected postoperative result.
04
Intraocular Lens Measurements
Precise measurement of axial length and corneal curvature to calculate the appropriate intraocular lens power.
05
Selecting the Lens Type
Discussion of monofocal, enhanced monofocal, extended-depth-of-focus, and multifocal lenses according to ocular suitability.
06
Understanding the Patient’s Needs
Considering work, driving, reading, device use, and the desire to reduce dependence on glasses.
07
Precise Surgical Execution
Removal of the cataract and implantation of the selected lens using modern surgical techniques and an individualized plan.
08
Postoperative Follow-up
Monitoring recovery, eye pressure, wound healing, and visual improvement, with clear instructions and an eye-drop schedule.
09
Clear Discussion of Expectations
Explaining the expected result and limitations of each lens type before the final decision.
Vision Ranges
What Is the Difference Between Distance, Intermediate, and Near Vision?
The benefit of each lens depends on the range for which it is designed to provide the best clarity, and glasses may still be needed for some distances after surgery.
Usually Beyond 2 Meters
Distance Vision
For activities requiring clear vision of distant objects.
Driving and Viewing the Road
Watching Television
Recognizing Faces at a Distance
Approximately 60–100 cm
Intermediate Vision
For daily tasks between reading distance and far vision.
Computer Screen
Car Dashboard
Cooking and Office Work
Approximately 33–50 cm
Near Vision
For detailed tasks performed close to the eyes.
Reading a Book or Phone
Sewing and Fine Tasks
Reading Medication Labels
Types of Intraocular Lenses
A Simple Comparison to Help You Understand the Options
The following table is for general guidance. Final lens selection depends on corneal, retinal, and optic nerve health, ocular measurements, and your everyday visual needs.
| Lens Type | Distance Vision | Intermediate Vision | Near Vision | Expected Dependence on Glasses | Simple Notes |
|---|---|---|---|---|---|
| Monofocal | Usually excellent when targeted for distance | Limited | Limited | Glasses are often needed for computer work and reading | Good clarity and optical simplicity; suitable for many patients. |
| Enhanced Monofocal (Monofocal Plus) |
Usually excellent | Better than traditional monofocal | Limited | May reduce the need for intermediate glasses, while reading glasses are still often required | Provides a modest extension of vision while retaining characteristics similar to a monofocal lens. |
| Extended Depth of Focus (EDOF) |
Very good to excellent | Usually very good | Moderate and may not be sufficient for small print | Glasses may be needed for some fine reading tasks | A useful option for patients prioritizing distance and computer vision while reducing dependence on glasses. |
| Trifocal | Very good | Very good | Usually good | Less dependence on glasses across most distances | Some patients may experience glare or halos at night; careful patient selection is important. |
Results vary between patients, and no single lens is ideal for every eye or every visual need.
Toric Lenses for Astigmatism Correction
Treat Cataract and Astigmatism in the Same Surgery
In some cases, replacing the cloudy lens alone is not enough because corneal astigmatism can affect postoperative visual clarity. Toric intraocular lenses are available to correct astigmatism during cataract surgery after detailed measurements of each eye.
Why Might a Toric Lens Be the Better Option for You?
Lens power and axis are selected from corneal measurements and astigmatism magnitude to improve visual quality and reduce dependence on distance glasses as much as possible.
Customized Correction for Each Eye
A single lens is not used for everyone; power and axis are calculated according to your eye measurements.
Clearer Distance Vision
May reduce blur and ghosting caused by astigmatism after cataract removal.
Reduced Dependence on Glasses
Especially for distance glasses, although expected results vary according to ocular condition.
Precise Preoperative Measurements
We review corneal maps and astigmatism axis to select and orient the lens carefully.
Toric
Not Every Astigmatism Requires the Same Lens
We discuss the degree of astigmatism, corneal condition, visual needs, and lifestyle before recommending a lens. The goal is not to sell a particular lens, but to select the lens that gives your eye the best opportunity for stable, clear vision.

We Use iTrace to Help Select the Most Suitable Lens for Your Eye
The device combines optical aberration analysis with corneal mapping to help identify the source of reduced visual quality and assess suitability for selected advanced lenses.
✓Analyzes overall visual quality, not only the glasses prescription.
✓Helps distinguish the contribution of the cornea from that of the natural lens to visual quality.
✓Evaluates the visual axis and pupil center and their relationship to selected advanced lenses.
✓Supports a clearer discussion of expected options before surgery.
When Might You Need Surgery?
When Cataract Begins to Affect Daily Life
The decision for surgery is based on how reduced vision affects daily life, not only on the cataract grade seen during examination.
✓
Increasing Blur or Reduced Vision
Especially when daily activities become difficult to perform comfortably.
✓
Increasing Night Glare
Such as difficulty driving or discomfort from headlights and other lights.
✓
Faded Colors or Reduced Contrast
When images appear less clear or colors seem less vivid.
✓
Frequent Changes in Glasses Prescription
When updating the prescription no longer provides sufficient improvement.
✓
Reading or Work Is Affected
When reduced vision interferes with reading, device use, or work tasks.
