What is the difference between trifocal and monofocal IOLs?

Monofocal lenses provide clear vision at only one distance (usually far), still requiring reading glasses for near tasks. Trifocal lenses use diffractive ring design to distribute light to far, intermediate, and near focal points, achieving full-range clear vision and greatly reducing spectacle dependence.

Will I truly not need glasses after surgery?

Many carefully selected patients achieve substantially reduced dependence on glasses, but complete spectacle independence is not guaranteed. Fine reading, dim-light tasks, or residual refractive error may still require supplementary spectacles.

Is the halo problem significant?

The optical design of multifocal lenses causes some degree of halos and glare, especially at night. Most patients neurally adapt within 2-3 months without impact on daily life or night driving.

Trifocal IOL Implantation

Trifocal Lens ReplacementMultifocal IOL SurgeryPresbyopia-Cataract Combined Surgery

After careful selection, implantation of a trifocal intraocular lens can reduce spectacle dependence in patients with presbyopia and cataracts while balancing far, intermediate, and near vision.

The surgical procedure is broadly the same as standard cataract phacoemulsification, except that a presbyopia-correcting trifocal diffractive IOL is implanted (for example, Zeiss AT LISA tri or Alcon PanOptix). These lenses can help balance far, intermediate, and near vision and reduce dependence on glasses, but they do not guarantee complete spectacle independence for every patient. Outcomes are influenced by corneal astigmatism, ocular surface status, macular function, residual refractive error, and neural adaptation. This option is best suited to carefully selected middle-aged or older patients with presbyopia and early cataract.

Who Is This For

Is Trifocal IOL Implantation Right for You?

Good Candidates

Middle-aged and older patients with presbyopia and cataracts who pass careful preoperative screening
Those with strong desire for spectacle independence
People frequently switching between far, intermediate, and near distances
Active individuals with high quality-of-life expectations

May Not Be Suitable

Significant uncorrected astigmatism >1.5D (toric trifocal needed)
Severe fundus disease affecting vision
Extreme sensitivity to halos or very high night driving demands
Pupil too large or too small

Step-by-Step Process

How Trifocal IOL Implantation Works

Preoperative preparation

Pupil dilation, topical anesthesia, sterile draping.

Corneal incision

Create a 2.2-2.4mm clear corneal incision.

Capsulorhexis and hydrodissection

Continuous curvilinear capsulorhexis and hydrodissection to mobilize the lens nucleus.

Phacoemulsification

Ultrasonic emulsification and aspiration of the cloudy or clear lens.

Trifocal IOL implantation

Inject the folded trifocal IOL into the capsular bag and adjust position.

Completion

Irrigate residual cortex, hydrate wound for self-seal closure, no sutures needed.

Single procedure per eye. Both eyes typically done 3-7 days apart.

Cost Information

Cost Estimate for Trifocal IOL Implantation

Estimated Price Range

¥3,657.83 – ¥9,510.34

What's Included

Public tier-3A International Medical Department: approximately ¥25,000-38,000 per eye (with imported trifocal IOL); premium private eye hospitals: approximately ¥35,000-65,000 per eye (with high-end imported trifocal lenses such as Zeiss AT LISA tri or Alcon PanOptix and systematic postoperative follow-up). The trifocal lens itself accounts for approximately 70% of the cost.

Before Your Visit

What to Prepare

Required Tests & Examinations

If you already have recent valid test results, bring the reports. If not, these assessments can usually be completed in China before the procedure.

Cycloplegic refraction

Corneal topography (rule out irregular astigmatism)

Axial length and corneal curvature (IOL power calculation)

Corneal endothelial cell count

Macular OCT

Dry eye evaluation

Documents & Materials to Bring

Required to Bring

Passport and valid visa

Previous refraction and eye examination records

Systemic medical history

Companion & Support

Accompaniment needed on surgery day.

After Treatment

Recovery & Follow-Up

Normal eye use possible from the next day

Vision recovers quickly but full adaptation to all distances takes 1-3 months

Mild nighttime halos initially; most people adapt

Use prescribed anti-inflammatory and antibiotic eye drops

Avoid swimming and strenuous exercise for 1 month

Avoid rubbing eyes

Follow-Up Schedule

Follow-up at 1 day, 1 week, 1 month, and 3 months post-surgery.

Conditions This Procedure Treats

Presbyopia

An age-related physiological change where decreasing lens elasticity leads to reduced accommodation and difficulty focusing on near objects.

Cataract

A common eye condition where the natural lens becomes cloudy, causing progressive vision loss. When vision is meaningfully affected, surgery is the main effective way to restore visual function.
