Scaling Premium IOL Production

April 19, 2026

Scaling Premium IOL Production: Why the QC Model That Works at 5,000 Lenses Breaks at 15,000

The board approved the growth plan. Premium IOL production will triple within 18 months-from 5,000 lenses per week to 15,000, with EDOF growing from 10% to 40% of the mix.

Zernike Decomposition for EDOF IOL Characterization

April 19, 2026

Zernike Decomposition for EDOF IOL Characterization: A Practical Guide to the Modes That Matter

The wavefront measurement is complete. The Zernike decomposition report arrives: 36 polynomial coefficients, each quantifying a specific aberration type across the lens aperture.

EDOF Tolerance Analysis: Using Measured Manufacturing Variability to Predict Production Yield

April 19, 2026

EDOF Tolerance Analysis: Using Measured Manufacturing Variability to Predict Production Yield

The optical design is complete. The through-focus simulation shows a plateau of 1.6D at 3mm aperture and 1.1D at 4.5mm. The sensitivity analysis confirms that ±10% variation in each spherical aberration coefficient keeps the plateau above the minimum acceptance threshold.

EDOF intermediate vision design for 60–80cm working distance

April 16, 2026

Designing EDOF for Enhanced Intermediate Vision: Optimizing the 60–80cm Range

The global intraocular lens market reached approximately $4.9 billion in 2025. Premium IOLs-toric, multifocal, EDOF, and accommodating designs-are growing at roughly 7–7.5% CAGR, outpacing the overall IOL market by a significant margin.

EDOF IOL market opportunity and QC investment timeline

April 16, 2026

EDOF Market Opportunity and the QC Investment Timeline: Why Quality Infrastructure Must Lead Volume Growth

The global intraocular lens market reached approximately $4.9 billion in 2025. Premium IOLs-toric, multifocal, EDOF, and accommodating designs-are growing at roughly 7–7.5% CAGR, outpacing the overall IOL market by a significant margin.

reverse engineering competitor EDOF IOL optical characterization

April 16, 2026

Reverse Engineering Competitor EDOF: Optical Characterization Methods for Competitive Analysis

A competitor launches a new EDOF IOL. The marketing material describes it as “extended depth of focus with minimal dysphotopsia.” The surgical community reports enthusiastic early adoption. The competitor’s sales are growing in accounts where your EDOF was previously preferred.
