Expanding the Clinical Toolkit: Practical Strategies for Comorbidity Management

Managing HHS in thee era of diabetic lens technologiy implis rethinking traditional protocols. Below are actionable strategies that leverage real-time, lens- derived data alongside conventional care.

Te first step is to ensure that data from thee diabetic lens (glukose, IOP, hydration proxy) flows into a central hospital monitoring system.
