Quickguide.org is an informal educational resource specifically for eye care professionals focusing on biometry, intraocular lens (IOL) power calculation, and advanced optics.
Educational Value and Content
This site offers deep technical insights into cataract surgery preparation. Its educational strengths include:
Complex Concepts Simplified: It provides "guides" on advanced optics, such as spherical aberration, diffractive orders in multifocal lenses, and Zernike polynomials.
Practical Calculation Tools: The site hosts several free interactive tools, including:
A-constant Optimization: Tools to convert immersion ultrasound constants to optical biometry constants.
Post-Op Predictors: A calculator to match predicted effective lens position (ELP) with actual postoperative ACD.
Second Eye Predictor: A calculator that uses first-eye prediction errors to refine second-eye IOL selection.
Formula Deep-Dives: It offers detailed explanations of formula generations, specifically analysing how modern formulas like Barrett Universal II, Hill-RBF, and Kane handle unusual eye parameters.
Specialized Clinical Scenarios: The platform covers niche topics such as IOL power calculation challenges in keratoconus and post-LASIK patients.
Format and Accessibility
Multimedia Approach: Education is delivered through long-form articles (some up to 20-minute reads), short "quick guides," and video presentations.
Supplemental Video Content: The site is linked to a YouTube channel (quickguide_subha) that provides visual walk-throughs of biometry and phacoemulsification basics.
Target Audience: While labelled as "Beginner's Guides," the content's depth is most suitable for ophthalmology residents, optometrists, and biometry technicians.
For industry professionals looking for a free alternative to subscription driven academic journals , quickguide.org is an excellent resource for staying updated on the evolving "art and science" of IOL power selection. It effectively bridges the gap between raw data from biometry machines and successful clinical outcomes.
