No. Between 5% and 10% of patients require an enhancement. A smaller proportion experience complications requiring active management. This is the expected distribution of outcomes in a biological system, not a failure rate.
Contemporary large-scale outcome studies place enhancement rates following LASIK at 1-5% for low to moderate myopia and up to 10% for high myopia. Transient dry eye affects 20-40% of patients in the early months. Clinically significant corneal haze follows surface ablation in fewer than 2% of patients treated with modern protocols. ¹
These are not rare edge cases. They are the expected minority outcomes across a population with biological variability. Presenting them as rare failures is misleading. Presenting them as uninformative averages is equally unhelpful.
What Biological Variability Actually Means
Laser platforms deliver highly precise ablations. What they cannot control is the corneal healing response. Keratocyte activity, epithelial remodelling, corneal biomechanics, and individual neural adaptation to refractive change are not fully predictable from preoperative assessment. Even with optimal patient selection and technique, a proportion of patients will experience an outcome outside the intended target range. ²
In practical terms: If 100 patients have TransPRK on the same day with the same surgeon on the same platform, they will not all achieve identical results. The ablation is precise. The healing is biological.
What the Data at Blue Fin Vision® Shows
Mr Hove submits outcome data to the National Ophthalmology Database across four consecutive years. Refractive outcomes and complication rates are reviewed against national benchmarks annually. This creates a feedback loop between outcomes and practice that most private refractive providers do not have. ³
Enhancement rates and complication frequencies by procedure and refractive profile are discussed at preoperative consultation, in the context of the individual patient, not as aggregate statistics.
What to Ask Instead of ‘What Is Your Success Rate?’
Most patients ask: what is your success rate? A more revealing question is: what happens if I am in the minority who need more attention?
At Blue Fin Vision®, the answer to that question is a documented clinical pathway, structured follow-up, a written enhancement policy, specialist colleague access, and named-surgeon continuity throughout.
Blue Fin Vision® specifically: Mr Hove has personal experience as a refractive surgery patient, having undergone bilateral trifocal IOL implantation. This experience informs the clinical consultation process at Blue Fin Vision®: the recovery trajectory, the variability of early visual quality, and the point at which concern is warranted versus when observation is appropriate are not theoretical positions here.
When things are straightforward, many clinics perform well. When they are not, that is where systems, experience and accountability matter most.
Frequently Asked Questions
Is a 95% success rate good for laser eye surgery?
In the context of elective surgery on a healthy visual system, a rate of achieving within 0.50 D of the intended correction in approximately 95% of eyes is the benchmark achieved by experienced centres. The 5% who do not achieve this on the first procedure are typically eligible for enhancement. The total proportion achieving spectacle independence across both the primary procedure and enhancement is higher.
Why does Blue Fin Vision® not publish a single headline success rate?
Because a single figure without context is clinically misleading. Enhancement rates for low myopia differ from those for high myopia. Surface ablation recovery differs from LASIK. A headline rate that averages across these produces a number that does not apply to any individual patient. At consultation, the relevant outcome data for the specific procedure and correction being considered is discussed directly.
Does Mr Hove’s personal surgical experience make a difference to how he consults?
It should, and at Blue Fin Vision®, it does. The experience of bilateral trifocal IOL implantation informs how Mr Hove describes the recovery trajectory, what early visual variability feels like from the patient’s perspective, and which concerns are worth raising versus which are part of the expected course. This is clinical experience that cannot be acquired from published literature.
