Introduction
YAG capsulotomy is a laser procedure used to treat posterior capsule opacification (PCO), a common cause of blurred vision after cataract surgery.
On 3rd April 2024, I underwent cataract surgery.
On 19th March 2026, I underwent a YAG capsulotomy.
Between those two dates lies a journey I have guided thousands of patients through, but this time, I experienced it from the other side of the slit lamp.
YAG capsulotomy is often described as a quick, simple laser procedure. Clinically, that is true. Experientially, it is more nuanced.
My journey is more complex than that of most people having routine cataract surgery, but the principles and experiences I describe are highly relevant to anyone considering or recovering from cataract surgery, or to anyone who has been told they may need a YAG capsulotomy.
The Context: From Uveitis to Cataract to PCO
My cataract was not age-related. It developed as a direct consequence of two intersecting processes: a history of uveitis (chronic inflammation inside the eye), and the prolonged use of topical corticosteroids required to manage it.
Prolonged steroid use and intraocular inflammation are both well-established causes of a specific type of cataract called a posterior subcapsular cataract – a cataract that forms at the back of the lens and tends to cause particular difficulty with glare, bright light, and reading, often developing earlier and more rapidly than the type of cataract associated with normal ageing. ¹ ²
Following cataract surgery, there is a well-recognised phenomenon called posterior capsule opacification, sometimes described to patients as “after-cataract” or a film that forms behind the lens implant. It occurs when cells remaining after surgery slowly migrate across the back of the capsule (the thin membrane that holds the implant in place), causing a gradual return of haziness. ³ ⁸ In eyes with a history of uveitis, this process tends to occur faster and more frequently than in eyes undergoing routine age-related cataract surgery.
For me, PCO became clinically apparent just under two years following surgery. Within the context of a uveitic eye, this is not unexpected, but it is a trajectory that patients in this group deserve to understand clearly from the outset. ⁴
YAG laser capsulotomy treats this by creating a small, precise opening in the opacified capsule, restoring a clear optical pathway. It is highly effective, typically permanent, and carries a well-characterised safety profile. ⁵
My original surgery was performed by Mr Bizrah. My intention was always for him to complete the journey. When I learned he was unable to return from Dubai – circumstances entirely beyond anyone’s control – he arranged, with characteristic professionalism, for his colleague Mr Mohammed Elafy to see me in his absence. I remain deeply grateful to both of them: to Mr Bizrah for ensuring continuity of care from a distance, and to Mr Elafy for stepping in with such precision and care.
My pre-procedure visual acuity was 6/5 in the right eye and 6/6 in the left, both within the range most people would consider excellent. But I had already noticed the change: a subtle loss of contrast, a gentle haze that had not been there before. I owe it to my patients to operate at my best. I did not want to wait.
What YAG Capsulotomy Actually Feels Like
Even as a surgeon who performs this procedure, several aspects stood out.
Keeping both eyes open is harder than expected.
There is a natural tendency to blink or close the eyes as the laser is delivered. This is something we routinely guide patients through, but experiencing it directly reinforces how important that guidance is.
Even knowing the evidence, there is still a flicker of apprehension.
Even knowing the procedure inside out – the mechanism, the risks, the expected outcome – I still felt the normal flicker of apprehension that many patients describe in the chair. That is not weakness. It is a completely understandable response to having a laser directed at your eye. Acknowledging it, rather than dismissing it, is part of good patient care.
OCT was performed as standard – without discussion.
There was no debate about whether imaging was required. It was simply performed. This reflects a shift in modern practice: confirming the correct diagnosis and excluding alternative causes of blurred vision – such as fluid at the back of the eye (cystoid macular oedema) or macular disease – is now embedded as standard before capsulotomy, particularly in eyes with a history of inflammation. ⁶
The laser has a distinct sensory signature.
Each pulse produces a perceptible “pop” – not loud, but noticeable. What surprised me was how internal it felt: as though the sound originated within the head rather than externally. It is not uncomfortable. But it is distinctive, and worth describing to patients before the procedure, rather than leaving them to encounter it without context.
The Professional Dynamic: When the Patient Is a Colleague
Undergoing a routine procedure within one’s own professional community subtly changes the dynamic.
The stakes are not higher clinically – the procedure remains the same. But there is an increased awareness in the room. Precision, always essential, feels even more deliberate. There is also an unspoken layer of mutual respect and trust that is rarely discussed outside professional circles, and which speaks well of this specialty.
The Outcome: Clarity Restored
The effect of YAG capsulotomy is often immediate. Vision sharpens. Contrast improves. The subtle haze lifts. ⁵
From a clinical perspective, this is expected. From a personal perspective – sitting in the patient’s chair rather than standing at the slit lamp – it is still striking.
When Should You Consider YAG Capsulotomy?
PCO does not always cause symptoms immediately, and not everyone who develops it will require treatment. The decision to proceed with YAG capsulotomy is based on symptoms, not just visual acuity.
The symptoms that most commonly indicate PCO has become clinically significant include:
- Haze after cataract surgery. A gradual return of mistiness or blur, distinct from the clarity experienced in the weeks following the original operation.
- Glare and haloes. Increased sensitivity to bright lights, oncoming headlights at night, or halos around light sources.
- Reduced contrast. Colours may appear less vivid, and the distinction between objects and their backgrounds becomes less defined.
- “Film over vision.” Many patients describe the sensation as looking through frosted or dirty glass, a sense that the lens itself has changed, even when it has not.
Even with 6/6 vision, patients may notice meaningful degradation in visual quality. The decision to proceed is based on symptoms, not just visual acuity.
This was precisely my own experience. My acuity measured 6/5 and 6/6, within the range considered excellent. But the subjective quality of my vision had shifted, and that shift mattered. As a surgeon, I recognised it. As a patient, I felt it.
What I Do Differently For My Patients Now
Experiencing the procedure from the patient’s side has reinforced several principles that underpin the Blue Fin Vision® approach:
- Aetiology shapes the entire trajectory. A patient with uveitic or steroid-induced cataract faces a different post-operative course than one with age-related disease. Understanding that distinction from the outset enables more accurate counselling and earlier recognition of PCO.
- Diagnosis matters as much as treatment. Imaging and careful clinical assessment ensure the correct problem is being addressed before the laser is applied, particularly important in eyes with a history of inflammation.
- Visual acuity alone does not tell the full story. A patient can retain measurably good vision on a chart and still notice meaningful deterioration in contrast, clarity and quality of vision. Both dimensions matter.
- Patients deserve to know what to expect. Small details – what the laser sounds and feels like, the flicker of apprehension beforehand, the floaters that may follow – shape the experience in ways that clinical descriptions alone do not capture.
- Technique and judgement remain critical. Avoiding damage to the lens implant, managing energy delivery carefully, and selecting the correct capsulotomy size are not visible to patients, but they determine outcomes. ⁷
- Aftercare and reassurance are part of the treatment. Floaters following YAG are common and typically self-resolving, but without explanation they can be alarming. The post-procedure conversation is not a formality.
A Final Perspective
It is easy to describe YAG capsulotomy as quick and straightforward. And it is.
But from the patient’s side, even the most routine procedures carry sensory experiences, psychological nuances, and moments of uncertainty that clinical descriptions do not fully convey.
Having now experienced both sides – surgeon and patient – that perspective is clearer than ever.
Conclusion
Uveitis led to a cataract. The cataract required surgery. Surgery, in due course, led to PCO. PCO required a YAG capsulotomy.
Each step was clinically predictable. Each step was manageable. And each step was part of the same continuum of care.
Understanding that continuum, not just clinically, but experientially, is what defines truly patient-centred practice.
