About the service
Phacoemulsification removes the cloudy lens through a small incision and is followed by IOL implantation. Lens parameters are calculated before surgery according to eye health and visual needs.
Who the service is for
Cataract and lens condition
Glare, halos, reduced contrast or night-vision problems are clinically attributable to cataract. Spectacle correction no longer provides the required visual quality because of lens opacity. The cataract limits examination or treatment of the retina, macula or other posterior-segment structures.
Laser correction for astigmatism
Cataract coexists with regular astigmatism and a toric IOL is being considered.
Cataract and lens condition
Zonular weakness or complicated cataract requires a modified surgical strategy. Cataract coexists with glaucoma or vitreoretinal disease and combined surgery is being considered.
Realistic expectations
Surgery cannot guarantee a particular visual acuity because the final result also depends on the cornea, macula, retina, optic nerve, glaucoma, diabetic changes and other ocular conditions. An IOL does not restore the natural accommodation of a young crystalline lens; spectacles or adaptation to optical phenomena may still be needed even with advanced IOL designs.
Retinal tears and detachment
Potential complications include inflammation, elevated intraocular pressure, corneal or macular edema, posterior capsule rupture, IOL decentration/dislocation, infection, retinal detachment and others.
Travel after the appointment
Cataract-related visual loss interferes with reading, work, driving, mobility or usual daily activities.
Do not change medicines yourself
Preoperative eye assessment and IOL calculation are required. Bring previous ophthalmology reports, records of prior eye surgery and a complete medication list. Tell the surgeon about diabetes, anticoagulants or antiplatelet drugs, drug allergies, glaucoma, retinal disease, eye trauma, previous laser vision correction and any known difficulty with pupil dilation. Do not stop systemic medicines on your own.

Prescribed medicines
KazRIED should provide the exact tests, consultations and preoperative medication schedule for the chosen treatment format.
When urgent care is needed
Severe pain, marked redness, sudden visual loss, a curtain-like shadow, flashes or a rapid increase in floaters require urgent assessment.
Limitations and safety
Surgery cannot guarantee a particular visual acuity because the final result also depends on the cornea, macula, retina, optic nerve, glaucoma, diabetic changes and other ocular conditions.

Stages
Stage 1
Preoperative diagnostics
Cataract is confirmed and visual potential and risk factors assessed.
Stage 2
Biometry and IOL selection
Axial length and corneal curvature are measured and the target refractive outcome discussed.
Stage 3
Day-of-surgery preparation
Document and eye checks, pupil dilation, antisepsis and the selected anaesthesia.
Stage 4
Microincision and capsulorhexis
The surgeon creates an incision and performs anterior capsulorhexis.
Stage 5
Phacoemulsification and aspiration
The opaque lens is fragmented by ultrasound and removed, preserving the capsular bag where possible.
Stage 6
IOL implantation
A foldable lens is inserted into the capsular bag or secured differently if standard fixation is impossible.
Stage 7
Completing surgery
Incision sealing and the anterior segment are assessed; sutures are used only if needed.
Stage 8
Postoperative review
The patient receives a drop regimen, restrictions and review schedule; recovery depends on the method, eye health and associated conditions.
Service benefits
Removal of the cloudy lens
The ultrasound technique allows removal of the lens affected by cataract.
A small surgical incision
Phacoemulsification uses a small incision to remove the lens and insert an IOL.
Replacement of the lens's optical function
When IOL implantation is possible, the artificial lens replaces the optical function of the removed lens.
An option for combined treatment
When indicated, the surgeon can combine cataract treatment with another necessary eye operation.

Cataract phacoemulsification with IOL implantation
A cataract reduces the transparency of the natural lens, allowing less light to reach the retina. Images become cloudy and less contrasted, glare appears, and vision deteriorates during everyday activities.
How is the operation performed?
Phacoemulsification addresses the optical cause of cataract-related visual impairment. The surgeon makes a small corneal incision and creates an opening in the anterior lens capsule.
An ultrasound probe is then used to fragment and aspirate the clouded lens material, preserving the capsular bag whenever possible.
A foldable intraocular lens (IOL) with a precalculated optical power is implanted through the same incision.
What does the choice of IOL affect?
The lens type affects focusing after cataract removal, the ability to correct astigmatism, and dependence on glasses at different distances.
When are additional procedures needed?
In cases of zonular weakness, dense or complicated cataract, glaucoma, or vitreous or retinal disease, the surgical plan may include:
- placement of a capsular tension ring;
- an alternative method of IOL fixation;
- a combined operation.
The patient therefore needs an agreed treatment plan based on diagnostic findings and the expected visual benefit.
How is surgery planned at KazRIED?
At KazRIED, the surgical approach, IOL type, and need for additional procedures are determined after a diagnostic assessment.
Planning considers cataract density, the condition of the cornea, retina, optic nerve, and lens zonules, as well as the patient’s visual needs.
Additional advice and situations
When an expanded plan is needed
An expanded pathway is particularly relevant for complicated or dense cataract, zonular weakness or lens subluxation, significant astigmatism, glaucoma, diabetic retinopathy, epiretinal membrane, macular disease, high myopia, previous vitreoretinal surgery or prior corneal laser correction.
These situations may require additional testing, a capsular tension ring, a toric IOL, combined glaucoma/vitreoretinal surgery or an alternative lens-removal technique.
Intraocular-lens selection
Phaco + IOL + capsular tension ring: For zonular pathology when indicated.
Crystalline-lens condition
Phaco without IOL: For specific surgical indications only.
Tunnel extracapsular cataract extraction + IOL: Alternative method, not the same as standard phaco.
Phaco + IOL + trabeculectomy: Combined cataract-glaucoma operation.
Intraocular-lens selection
Phaco + IOL + vitrectomy + silicone/PFCL: Complex combined vitreoretinal procedure.

Frequently asked questions
What is cataract phacoemulsification?
Phacoemulsification is cataract surgery in which the cloudy natural lens is fragmented with ultrasound and removed through a small incision. An intraocular lens is then usually implanted.
Is phacoemulsification the same as cataract removal?
Phacoemulsification is the principal modern technique for surgical cataract removal, but it is not the only possible technique. Another approach may be chosen in selected anatomical or clinical situations.
Must I wait until the cataract is mature?
No. Surgery is considered when cataract significantly interferes with vision, daily activities or management of other eye disease. Waiting for a “mature” cataract is not required.
Is there a fixed visual-acuity threshold for surgery?
No single visual-acuity threshold applies to every patient. Symptoms, visual needs, effect on daily life, ocular health and expected benefit are considered.
Can eye drops cure cataract?
No. Eye drops and medicines cannot restore transparency to an already cloudy natural lens. Surgical removal of the cloudy lens treats the cataract itself.
What replaces the removed natural lens?
An artificial lens, or intraocular lens, is usually implanted after cataract removal. Its optical power is calculated before surgery from ocular measurements.
How is an IOL selected?
Selection considers ocular biometry, corneal curvature, astigmatism, corneal, macular and optic-nerve health, previous surgery and the patient’s visual goals. The intended postoperative refractive target is also defined.
What is a toric IOL?
A toric IOL contains a cylindrical component designed to reduce suitable regular corneal astigmatism at the time of lens replacement. Accurate measurements and proper alignment are important.
What is a multifocal IOL?
A multifocal IOL uses a specialized optical design intended to reduce spectacle dependence at multiple distances. It is not suitable for every patient and can be associated with optical phenomena such as halos and glare.
Will I still need glasses after surgery?
Possibly. Spectacle dependence depends on the IOL design, refractive target, pre-existing and residual astigmatism, ocular health and individual outcome.
