The Days of Inventory on Hand (DOH) for Glaukos Corporation have been gradually increasing over the past eight quarters. In Q4 2023, the DOH stood at 202.78 days, compared to 196.47 days in Q3 2023 and 199.26 days in Q2 2023. This upward trend indicates that the company is holding onto its inventory for a longer period before it is sold.

Looking back to Q1 2022, there has been a noticeable increase in the DOH from 134.49 days to over 200 days in the latest quarter. This may suggest potential inefficiencies in inventory management or slower inventory turnover, impacting the company's liquidity and cash flow.

It would be advisable for Glaukos Corporation to closely monitor its inventory levels and assess the reasons behind the prolonged holding periods to optimize working capital and improve overall operational efficiency.
