Glasses and contact lenses
Reading glasses, varifocals and appropriate contact lenses can support close vision without lens replacement surgery.
Finding it harder to read your phone or small print? Explore presbyopia correction with George Voyatzis at Moorfields Private, including trifocal lens implants to reduce reliance on reading glasses.
Presbyopia is the gradual, age-related loss of the eye’s ability to focus up close. The natural lens becomes less flexible, so it can no longer change focus as easily between distant objects and nearby print. It commonly becomes noticeable in the forties.
You may hold your phone farther away, need brighter light or find small print tiring. It can affect people who have never worn glasses, as well as those who are short- or long-sighted. Presbyopia can develop while the lens is still clear; cataract is clouding of that lens.
Reading glasses, varifocals and suitable contact lenses can help. Surgery is an elective alternative for selected patients, following an assessment of eye health and visual priorities.
If your natural lens is cloudy, cataract surgery may address both cataract and presbyopia. If cataract is not the main reason for treatment, explore refractive lens exchange, also called lens replacement surgery. If there are no significant lens changes, PRESBYOND laser blended vision may be another option after specialist assessment.
If your natural lenses remain clear, with no significant cataract or other lens changes affecting vision, PRESBYOND may be considered as an alternative to lens replacement. It is a LASIK-based laser treatment that reshapes the cornea, the clear front surface of the eye, while leaving the natural lens in place.
The treatment increases the range of focus and usually plans one eye more for distance and the other more for near vision. The aim is for the two eyes to work together across everyday distances, reducing reliance on reading glasses.
A clear lens alone does not establish suitability. Assessment also considers your prescription, corneal shape and thickness, eye-surface health and how comfortably you tolerate the planned balance between the eyes.
PRESBYOND does not restore the natural lens’s flexibility, treat cataract or prevent cataract developing later. Glasses may still be needed, adaptation varies, and laser surgery has its own risks and visual trade-offs. These need a separate discussion before treatment.
During cataract surgery or refractive lens exchange, the natural lens is replaced with an artificial intraocular lens (IOL). A trifocal implant directs light into three main focal ranges: near for reading, intermediate for screens and distance for activities such as looking across a room.
Reading & phone
Computer & daily tasks
Looking farther away
These three “sweet spots” can substantially reduce dependence on spectacles. Useful vision may extend between them, but clarity varies with distance, lighting, the lens selected and your eyes. With Clareon PanOptix, the intended near and intermediate distances are approximately 40 cm and 60 cm.
A trifocal lens does not make the eye young again or restore the natural lens’s ability to change shape. It uses a different optical system, and your brain needs time to adapt.
Reading glasses may still help for small print, dim lighting or tasks requiring extra clarity. Halos, glare, starbursts and reduced contrast can occur, particularly at night. Symptoms can persist, and some people find them troublesome.
Corneal or retinal disease, dry eye, previous laser vision correction and important night-driving needs can affect suitability. A monofocal or EDOF lens may provide a better balance for some eyes. EDOF lenses mainly support distance and intermediate vision; reading glasses should be expected and computer glasses may also be needed.
Lens replacement also carries surgical risks. Discuss the benefits, alternatives and individual risks before deciding. Compare all lens options and read about visual effects and adaptation.
No. Presbyopia is the age-related loss of near focusing ability. Long-sightedness is a different focusing error; the two can occur together.
Yes. Glasses and contact lenses are common options. Selected patients may consider refractive lens exchange to reduce spectacle dependence before cataract develops, but the benefits must justify an elective operation.
PRESBYOND is a corneal laser treatment. It does not remove a cloudy natural lens. If lens changes affect your vision, cataract surgery or lens replacement may be more appropriate after assessment.
No lens guarantees freedom from glasses. Trifocal lenses aim to provide useful near, intermediate and distance vision. Glasses may still help for small print, dim light or demanding tasks.
No. They use a different optical system after the natural lens is removed. They do not restore its flexibility or prevent other age-related eye conditions.
A consultation considers your prescription, eye health, reading habits, screen use and night driving. Your surgeon will discuss alternatives, expected vision and individual risks before recommending treatment.
George Voyatzis FRCOphth is a Consultant Ophthalmic Surgeon at Moorfields Eye Hospital and Moorfields Private. Consultations take place at Moorfields Private, New Cavendish Street in Marylebone, and the Moorfields Private Outpatient Centre on Bath Street in the City Road area.
Your assessment, measurements and visual priorities guide the treatment discussion. View the London consultation locations and meet the practice team. Please confirm your appointment location when booking.
Most people are very happy with their vision following surgery. Although every effort is made to achieve the best possible visual outcome, I cannot guarantee that you will be satisfied with your vision following surgery.
A consultation will help establish which options suit your eyes and your priorities.
