Vision for
All Ages

Allon Barsam carefully customises all of his
treatments to fit the visual care needs of his
individual patients.

Mr Barsam’s unique experience and in-depth training in a range of associated specialist disciplines has led him to design and develop his own unique vision care for all ages system.

Targeting vision care to the individual is very complex and often age sensitive.

There are many options for the most appropriate treatment: advanced LASIK or advanced surface treatment (LASEK/epi-LASEK/PRK); implantable contact lens or a refractive lens exchange; or a combination in the form of Bioptics.

Mr Barsam has the skill, ability and experience to be able to assess each individual for the most appropriate option and personally carry out the procedure that is required to ensure the best vision care across all age groups.

Mr Barsam recognises that the ‘one treatment fits all’ approach is limited and may jeopardise patient outcomes, therefore he focuses on individualised vision care to ensure both optimum results and maximum safety.

The Vision Care For All Ages system

Mr Barsam has developed the Vision Care For All Ages system in order to fulfil several essential functions …


To specifically tailor treatment options to the individual needs, conditions and age of his patients.


To ensure that his patients benefit from fantastic vision not only at day one, month one and year one post surgery, but also for the decades that follow surgery.


To maximise the chance that his patients will only ever need surgery one time.

Age-Related Vision Problems

People in their 20s and 30s can benefit greatly from laser eye surgery. Their eyes have stabilised and they are busy starting their adult lives with new careers, active lifestyles and young children.

Correcting vision problems at this age is highly successful and permanent. Imagine not having to reach for your glasses in the middle of the night to go to a young child or swimming without contacts or glasses.

As you reach your mid-40’s, presbyopia is a common condition, making reading small print difficult. At this time, you may benefit from an enhancement to your original procedure to continue your glasses free life and help prevent vision loss.

Candidates in this age group must have a stable prescription and a comprehensive eye exam with Mr Allon Barsam to determine eligibility and the nature of their vision problems.

Procedures most suitable for this group are either Advanced Z-LASIKAdvanced Surface Ablation or Phakic IOLs.

Once you pass the age of 40, you may find that your vision is not what is once was, and this mild degeneration can continue into your 50s.

By the time you reach your 60s, it may become necessary to use glasses to help with everyday tasks such as reading or driving. You may find that you need more than one pair of glasses for different tasks. Again, this is perfectly normal, though you should speak to an ophthalmic consultant if you’re at all worried.

Many people in this age group finally chose eye correction surgery because they are starting to experience presbyopia and need to use bifocal, varifocal or reading glasses. Dry eyes are common too and can make wearing contact lenses more uncomfortable.

Even people that have never had vision problems may begin to suffer from blurry near vision at this age, making it difficult to read small print or complete close-up tasks such as threading a needle.

Laser eye correction surgery can correct visual errors such as nearsightedness, farsightedness and astigmatism, but Allon Barsam can also reduce the dependency on reading glasses for near vision with this age group.

Several options may benefit you …

Depending on your requirements and the specifics of your eyes, patients can choose from:


Blended Vision

  • Typically, the dominant eye is targeted for distance and the non-dominant eye is targeted for near to intermediate distances.
  • Not to be confused with monovision (blended vision is milder than monovision because there is less near correction in the non-dominant eye resulting in less difference between the eyes).
  • Far more people are able to adapt to blended vision than to monovision as there is no to little dissociation between the eyes.
  • The increase in depth of field, or range in vision, is achieved when the distance and near eyes overlap at intermediate distances.
  • The brain usually adapts to each eye focusing at a different distance within six to eight weeks, but it may take longer for you to adjust.
  • There may be some situations (such as night driving, performing fine detailed work or reading in poor lighting conditions) where you might require corrective lenses.

Refractive Lens Exchange

  • Also known as PreLex (Presbyopic Lens Exchange), Clear Lens Extraction or Clarivu, is the procedure of choice where both laser eye correction surgery and implantable contact lens surgery are not indicated, such as patients who have early lens changes, early cataracts or who are too far sighted to make the other treatments safe and effective.

The 60-plus age group often start to notice vision changes that require bifocal, varifocal, or reading glasses to see due to hardening of the lens in the eye. This is one of the most common age-related eye problems, where layers are added to the natural lens. This can result in the formation of a cataract and decreases the amount of light that can enter the eye, causing the vision to become yellow and blurry.

These vision changes are slow to progress, and gradually cause a decrease in the quality of vision but the formation of cataracts are different for everyone. Replacing the lens at this juncture is permanent and the need for cataract surgery is then eliminated.

As your body ages, many physical changes will occur, some of which can reduce your quality of life. While this is perfectly normal, changes to something as important as sight can be a frightening prospect.

Glasses can be prescribed for some age-related conditions, and advances in medical technology means that vision changes such as the development of cataracts need no longer be tolerated.

The good news is that cataract surgery is permanent and there should be no need for repeat surgery.

Common age-related eye conditions

  • Vision correction surgery is something you need to consider for more serious conditions such as cataracts. You can also have corrective surgery for conditions like presbyopia, which causes blurriness when looking at items close up, such as when reading, knitting, or using a computer.
  • By the time you reach your 60s, you should be having regular eye exams as well as regular physical examinations to identify related physical conditions which could affect your vision. Dry eye is common, particularly in older women, and this can cause discomfort. You may find your peripheral vision decreases, and that colours become more difficult to distinguish.
  • One of the most serious eye conditions is a detached retina. The symptoms of this include seeing spots and floaters in front of your eyes. While this can be attributed to increasing age and is often harmless, it will need to be checked by an ophthalmic professional as it could mean a detached retina, which will lead to blindness if it is not treated early.

Vision changes can mean that you need more light to see clearly than when you were younger. If you’re struggling to see at home then try using more lamps, especially when reading or doing other close-up work such as sewing.

Thankfully, most vision changes do not indicate serious health problems and their inconvenience and discomfort can be overcome using minor surgery, eye drops, or specialist glasses.

If you’re over 60 and recognise any of these symptoms, then make an appointment to see your optician.
