It is incumbent upon the operating surgeon to be familiar with all of these - and also to be familiar with their own outcomes with different formulas with different lenses in different eyes, and therefore to be able to choose the best power calculation for a given individual implantation https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/7d097553-908e-444f-b758-eab6e0ceb216/Screenshot+2025-07-09+161349.png News - Trifocals Step Forwards Three formulas indicate one optimum lens power, three indicate another. Which one would your surgeon use? Which formula is best for the optics and dimensions of that specific eye? Would you override the formula to put in a higher or lower power lens based on your experience of outcomes or to give the patient an outcome which is different from a standard one? https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/6ef29f49-99b6-4ab7-a84e-bb24b7133050/Screenshot+2025-07-08+190919b.jpg News - Trifocals Step Forwards - The primary element in the lens implant power calculation constellation is the measurement of the dimensions of the eye . All of the parameters meaured, whether they be corneal diameter, anterior chamber depth, axial length , corneal thickness, are getting better and better and approaching high levels of accuracy now . However, even with the latest formulas and methodology, eyes with previous corneal laser eye surgery can still have a relatively high degree of unpredictability in the final outcome optically. https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/1752052168591-TNM0NTS6II4BNUDCLMIN/Screenshot+2025-07-09+100852.png News - Trifocals Step Forwards https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/1752052268218-HZWKE86MLQGUOQIO5K3O/RayOne+EMVb.jpg News - Trifocals Step Forwards https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/22ffc43d-ae86-4b35-88f1-74c6c936f865/Screenshot+2025-07-08+190431.png News - Trifocals Step Forwards - The lens implant calculation is the use of formulas to calculate the power of the lens utilised . These formulas are actually getting better and better through previous first, second, third and the fourth generation formulas. Some are now incorporating AI to try and predict more accurately how a specific lens power will perform . https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/28e9c0b6-ddfc-4789-8ae6-4530493e8d55/WhatsApp+Image+2025-07-05+at+12.41.13_078b0151+o-2.jpg News - Trifocals Step Forwards - The quest for a lens implant which mimics the natural function of the lens continues! It is the dream of the ophthalmology profession to be able to have a lens implant which gives good vision from far distance all the way to up close for reading. We are yet to reach that goal but are making incremental steps forward. I implanted my first multifocal lens in 1998 and have have privileged over the years to have been the first surgeon in the Thames Valley, and one of the first in the country, to implant new generation extended depth of focus and multifocal lenses from Zeiss, Rayner , Johnson and Johnson and Alcon. In 2025 we have another step forward in lens design with the new generation trifocal lenses from Rayner (Galaxy lens) and JnJ ( Odyssey lens). I am delighted to be again the first surgeon in the Thames Valley to have implanted these lenses and to be able to give our patients the opportunity to benefit from the latest technology. https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/1752067485184-1FW1NUB191MP6K84CNR9/Screenshot+2025-07-09+142433.png News - Trifocals Step Forwards https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/1752067413452-M5HJQULW8PVGA4Q4WKZQ/97945-20115501.jpg News - Trifocals Step Forwards https://www.visioninsights.co.uk/news/blog-post-title-one-pemxn monthly 0.5 2025-04-20 https://www.visioninsights.co.uk/views daily 0.75 2025-10-06 https://www.visioninsights.co.uk/views/presbyopia-the-holy-grail-of-ophthalmology monthly 0.5 2025-10-06 https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/cb05aecf-1f86-4f47-9e91-2fbdaf33feb8/Generated+Image+October+05%2C+2025+-+6_53PM.png Blog and Views - Presbyopia: The Holy Grail of Ophthalmology? - Putting It All Together… So where does that leave us?

Will their increased use, and hence a higher incidence of patients presenting with complications, lead to any implications for eye care?

I saw the patient and, low and behold , an eyelash sitting just below the cornea in a horizontal line just under the conjunctiva. It must have been buried quite low in the fornix and not seen before and then migrated upwards. I gave some topical anaesthetic and scored the conjunctiva over the central 2mm with a needle – just as you would with splinter – to expose the middle of the lash and was able to pull it out smoothly without breaking it. https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/648be76c-11ff-4e35-a41a-acc69c46a0f4/thumbnail_IMG_3893.jpg Blog and Views - Sore eyes after cataract surgery - Some stinging from the post-surgery drops is very common – especially with drops such as Tobradex and Acular. This can be remedied by changing the drops if needed. If the eyes become more red and or more sore then there can be allergy to the medication or preservatives in them and, again, usually remedied by changing to a simpler preservative free drops regimen. Image left shows corneal staining from drops toxicity post cataract surgery having a significant impact on vision. https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/cb2ee40b-a14b-419e-9e82-f8f1e68f8f3d/Picture1.jpg Blog and Views - Sore eyes after cataract surgery - Ocular neuropathic pain: this is not just any eye pain - it is excessive pain or discomfort above what would be normally expected in the absence of significant clinical findings. It used to be called ‘pain without stain’, ie painful eyes in the absence of significant dry eye or other findings visible at the slit lamp. It can occur in patients with dry eyes but also can occur post surgery especially in patients who have had previous lasik and more so with some personality types. The pain sensation can be created in the nerves in the cornea but also sometimes centrally ( in the brain) or can be a combination of both. Pain receptors ( nociceptors) in the cornea https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/daf2b3e5-beec-4e8c-b35f-951fd8436e23/20241012_124225.jpg Blog and Views - Sore eyes after cataract surgery - Well, 28 years later I now have seen another patient with an eyelash in the anterior chamber and – yes – this time it was a patient I had operated on. What a surprise at the post op check! Again asymptomatic and no inflammation or redness but I elected to remove it as it was just in the wound internally and could have acted as a wick for infection to enter the eye. It was again straightforward to pull out by scoring the edge of the would and catching the edge of the lash to pull it out. Fortunately, it did not break or float away from me into the anterior chamber! I gave some intraocular antibiotics and all was well. https://www.visioninsights.co.uk/views/blog-post-title-one-ks3rc monthly 0.5 2025-04-20 https://www.visioninsights.co.uk/about daily 0.75 2025-06-07 https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/5de09f89-81e8-4465-a419-000e7e3a5527/Beaconsfield+SK+Photo.jpg https://images.squarespace-cdn.com/content/v1/67fea7d9779791441f4e0be0/e63f521c-b853-49fc-aa74-ca9697982124/Firefly+library+with+an+ocular+theme+in+sleek+style+and+old+books+on+shelves+65285-Recovered.png https://www.visioninsights.co.uk/home daily 1.0 2025-10-05 https://www.visioninsights.co.uk/subscribe daily 0.75 2025-06-07 https://www.visioninsights.co.uk/contact-1 daily 0.75 2025-06-07 https://www.visioninsights.co.uk/portfolio-3-2 daily 0.75 2025-05-09 https://www.visioninsights.co.uk/portfolio-3-2/new-portfolio-item monthly 0.5 2025-04-21 https://www.visioninsights.co.uk/portfolio-3-2/project-four-c9f4z-y7zgg monthly 0.5 2025-04-21 https://www.visioninsights.co.uk/portfolio-3-2/project-three-ph2n3-zxmrl monthly 0.5 2025-04-21 https://www.visioninsights.co.uk/portfolio-3-2/project-two-whgpe-ctbc9 monthly 0.5 2025-04-21 https://www.visioninsights.co.uk/portfolio-3-2/project-one-h346n-x8kkb monthly 0.5 2025-04-21 https://www.visioninsights.co.uk/portfolio-3-2/company-guides-to-oct monthly 0.5 2025-04-21
