When glaucoma is diagnosed, you may expect test results to change in a predictable and logical way. It can feel reassuring to believe that imaging scans and visual field tests will progress together. In reality, glaucoma rarely follows such a neat pattern, which often leads to confusion and concern. We monitor glaucoma using two main approaches: structural assessment and functional testing. Structural tests examine physical damage to the optic nerve and retinal nerve fibre layer. Functional tests assess how vision

When glaucoma is discussed, eye pressure is often presented as a fixed value. You may be told that intraocular pressure is “controlled” based on a single clinic measurement. In reality, eye pressure is dynamic rather than static. We recognise that it changes continuously across the day and night. We now understand that intraocular pressure follows a circadian rhythm. This means pressure naturally rises and falls over a 24-hour cycle. Factors such as body position, hormonal variation, and sleep patterns all

Glaucoma has traditionally been described as a condition driven mainly by raised intraocular pressure. You may have been told that lowering eye pressure is the primary aim of treatment, and this remains essential. We continue to rely on pressure reduction as a core strategy. However, pressure alone does not fully explain how glaucoma behaves in every individual. Growing evidence now shows that glaucoma shares characteristics with neurodegenerative diseases. Damage is not confined to the eye but involves progressive loss of

When glaucoma is discussed, intraocular pressure is often treated as the central issue. You may be told that lowering eye pressure is the primary goal of treatment, and while this remains important, it does not explain the full picture. Many people experience glaucoma progression even when their eye pressure appears well controlled. We now understand that glaucoma is a complex condition influenced by multiple factors working together. One of the most significant and often overlooked contributors is ocular perfusion pressure.

If you are considering LASIK surgery, one of the most important questions you may have is whether the results truly last. Short-term improvement can feel reassuring, but long-term stability is what ultimately determines confidence and value. You may wonder whether vision could slowly drift over time or remain reliable decades later. We believe these concerns are reasonable and deserve a clear, evidence-based explanation. LASIK has now been performed for more than two decades, allowing meaningful long-term data to be reviewed.

If you are considering LASIK surgery, you may hear your surgeon mention something called the optical zone. While attention is often placed on laser precision or recovery time, optical zone size plays a major role in how your vision feels after treatment. We understand that it influences comfort, night vision, and overall visual quality, not just sharpness. Gaining clarity on this topic can help you feel more confident in your decision. The optical zone refers to the central area of

If you’re researching LASIK surgery, you’ll often see discussions about visual quality, not just sharpness. Many people are surprised to learn that seeing clearly isn’t only about reading letters on an eye chart it’s about how your vision feels in real life.  At Eye Clinic London, we explain that higher-order aberrations play an important role in this experience. These subtle optical imperfections can affect how your eyes handle contrast, glare, and low-light situations. LASIK is very effective at correcting refractive

When you start exploring LASIK options, you’ll likely come across terms like wavefront-guided and wavefront-optimised. Both sound advanced and promise sharper, clearer vision, which can make the choice feel overwhelming at first.  At Eye Clinic London, we know that patients want clear scientific explanations rather than marketing buzzwords. Understanding the differences helps you make an informed decision about which approach may suit your eyes and lifestyle.  Both technologies are designed to correct subtle optical imperfections in the eye called higher-order

If you’re thinking about LASIK or have already had the procedure you may hear your doctor mention corneal nerves and healing. Many patients are surprised to learn that the cornea actually contains one of the highest concentrations of nerves in the body.  At Eye Clinic London, we often explain that understanding how these nerves recover can help you make sense of dry eye symptoms and overall visual comfort after surgery. Knowing what’s happening beneath the surface can put you at

Glaucoma eye drops are often the first treatment prescribed to lower eye pressure. Many patients use them for years with good control. However, some people continue to lose vision despite using drops correctly. When drops are no longer enough, it can feel worrying and confusing. You may wonder whether you have done something wrong or whether stronger treatment is risky. Understanding why this happens helps reduce fear. In this article, we explain why eye drops may fail, how glaucoma treatment
