Shares of Glaukos (GKOS) surged 9.77% in post-market trading on Wednesday, as investors reacted to the company's quarterly financial results and an optimistic full-year sales forecast.

The rally was sparked by Glaukos' second-quarter report, which showed net sales of $185.6 million, significantly exceeding the IBES consensus estimate of $150.9 million. Adjusted net income came in at -$8.3 million, also better than the -$12.3 million analyst projection. The company further boosted sentiment by issuing a full-year sales guidance of $680 million to $700 million, well above the consensus of $630 million.

The strong performance and raised outlook mark a continuation of the company's momentum, following a 5.07% gain during the regular session driven by a pipeline milestone and pre-earnings optimism.
