Advanced lenses and modern phacoemulsification machines are powerful tools, but the quality of planning often determines how well you see afterwards. Accurate biometry, detailed corneal mapping, retinal optical coherence tomography, and endothelial assessment all contribute to choosing the right lens power and type. Even small errors in axial length or corneal curvature measurement can result in noticeable refractive surprises.
Careful planning also identifies subtle macular or corneal conditions that may limit outcomes or influence lens selection. This prevents over‑promising, supports realistic expectations, and allows surgery to be tailored to your specific risks and goals. Technology enables precision; planning decides how that precision is used.
What this means for you
- The most important work often happens before you enter theatre.
- A thorough diagnostic pathway reduces surprises and improves long‑term satisfaction.
Questions to ask
- “What pre‑operative tests will you use to plan my surgery?”
- “How do these tests change the lens and target you recommend for me?”
