Presbyopia Surgery and Treatment: Options for Clear Near Vision

If you have started holding your phone at arm's length or reaching for brighter light to read a menu, you are noticing presbyopia, a normal change that eventually affects everyone. Glasses and contact lenses are the simplest answer. Presbyopia surgery is an option for people who want to depend less on reading glasses, and the approach that treats the problem where it arises is replacing the eye's natural lens.

This page explains the non-surgical and surgical options, who benefits most from lens-based correction, and how presbyopia treatment is planned with Prof. Dr. Elif Betül Türkoğlu in Antalya. For all lens operations, see lens replacement surgery.

What is presbyopia?

The US Food and Drug Administration describes presbyopia as the gradual loss of the eye's ability to change focus for close-up tasks, progressing with age. It happens in the crystalline lens behind the iris, which in young eyes changes shape to focus up close (accommodation). Over the years the lens stiffens, and near objects blur.

Typical signs are holding text farther away, needing more light to read and tired eyes during close work. Presbyopia does not damage the eye, but it adds to any existing prescription: nearsighted people can often read by taking their glasses off, whereas farsighted people may need help at every distance.

Non-surgical presbyopia treatment

• Glasses: reading glasses; bifocal or varifocal (progressive) glasses combining distance and near correction; office lenses for computer distance.
• Contact lenses: multifocal lenses, or monovision lenses with one eye corrected for distance and the other for near.

These carry little risk and can be updated as your eyes change. A few weeks with monovision contact lenses also shows whether monovision surgery would suit you.

What are the options for presbyopia surgery?

Lens replacement with a presbyopia-correcting lens

Lens replacement for reading vision uses the same operation as refractive lens exchange or cataract surgery: the natural lens is replaced with an intraocular lens, and its design determines how much near vision you gain.

• Trifocal and multifocal lenses focus at near, intermediate and distance. In the US trial of one trifocal lens (AcrySof IQ PanOptix), 49.6% of patients read at about 20/20 level at 40 cm without glasses, against 0.9% with a monofocal lens; at intermediate distance the figures were 73.2% and 22.5%. See trifocal lenses.
• Extended depth of focus (EDOF) lenses stretch focus from distance to arm's length. In the US trial of one EDOF lens (TECNIS Symfony), 76.9% reached 20/25 or better at intermediate distance (66 cm), against 33.8% with a monofocal lens; glasses may still be needed for small print. See EDOF lenses.
• Enhanced monofocal lenses extend intermediate vision slightly while behaving much like a standard monofocal lens.

More near focus has an optical price. A Cochrane review of 20 trials found halos about 3.6 times as likely with multifocal as with monofocal lenses. In the Symfony trial, 8.8% were "very bothered" by halos, against 1.4% with a monofocal lens; questionnaires differ between trials, so such figures should not be used to rank lenses. See choosing a lens.

Monovision or blended vision

Monovision sets one eye for distance and the other slightly nearer, with monofocal implants during lens surgery or with laser on the cornea. European guidance notes that monovision with lens implants gives good distance and intermediate vision with a low chance of halos. With monovision the eyes no longer work fully together, which can reduce depth perception, and not everyone adapts; a trial with contact lenses first shows whether it suits you.

Laser vision correction on the cornea

Laser treatments such as LASIK reshape the cornea and cannot restore the lens's focusing. The FDA cautions that people who used reading glasses before LASIK may still need them afterwards. Laser can create monovision, but the natural lens keeps aging, so near vision can keep changing, and a cataract can still develop later. See RLE vs LASIK and ICL.

Who benefits most from lens-based correction?

• People aged about 50 and over. US surgeons discuss lens exchange from about age 43, with the most suitable candidates typically over 50; younger people whose lenses still focus are usually poor candidates.
• Farsighted (hyperopic) people. Farsightedness combined with presbyopia is the most common reason for refractive lens exchange.
• People with early lens changes. One operation deals with presbyopia and the developing cataract; see cataract surgery.
• People not suited to corneal laser, for example because of dry eye or a thin cornea.
• People with otherwise healthy eyes and realistic expectations. European guidance reserves multifocal lenses for people who want to be free of glasses and accept the chance of halos.

What are the risks of presbyopia surgery?

Lens replacement carries the same risks as cataract surgery. UK patient guidance puts the chance of a serious complication at about 1 in 1,000, and multifocal designs add halos and glare. Highly nearsighted people need extra care, because lens surgery raises the risk of retinal detachment, especially in men under 60 with long eyes; see retinal detachment risk. Laser monovision carries the risks of corneal surgery, which the FDA lists as including severe dry eye, glare and halos. Each lens-surgery risk is explained in lens replacement risks and side effects.

How is presbyopia surgery planned?

1. Examination. Your prescription, near vision, eye length and corneal shape are measured, with a macular scan when needed; dry eye is treated first.
2. Your priorities. Reading, screens, night driving, work and hobbies, and how you feel about halos.
3. A trial where useful. Monovision contact lenses show whether you tolerate a different focus in each eye.
4. The plan. The lens for each eye, or monovision, and whether both eyes are treated on the same day.
5. Surgery and adaptation. A short operation under local anesthesia, then weeks to months of adaptation to multifocal optics; see recovery and flying home.

Presbyopia treatment in Turkey: care in Antalya

Prof. Türkoğlu performs cataract and lens replacement surgery in Antalya. She evaluates your eyes, explains which presbyopia options suit them, including when glasses or contact lenses remain the more sensible choice, and plans treatment with you. From abroad, you can send your current prescription and previous eye records before traveling; the measurements in Antalya then confirm the plan. The cost depends mainly on the lens and on whether one or both eyes are treated; see lens replacement costs.
