Pterygium is a common benign fibrovascular growth of the conjunctiva extending onto the cornea that\u00a0induces corneal distortion and astigmatism as it progresses. Following excision, transient keratometric instability may\u00a0occur, making the timing of refractive procedures dependent on the restoration of corneal stability.\nObjectives. The study aimed to identify the time to achieve keratometric stability after pterygium excision surgery\u00a0and associated factors.\nMethods. This was an observational retrospective cohort study of patients who underwent pterygium excision within\u00a0a period of 6 months. Data were abstracted from electronic medical records. The Kaplan-Meier method and log-rank\u00a0test were used to analyze the time to keratometric stability. Cox proportional hazards regression analysis was used\u00a0to identify the associated factors.\nResults. A total of 58 eyes that underwent pterygium excision from January 2022 to December 2023 were included\u00a0in the analysis. There was no statistically significant difference in terms of age, sex, laterality, polarity, and surgical\u00a0technique. Ninety-one percent (n=53) demonstrated keratometric stability three months after pterygium excision.\u00a0All eyes (100%) reached keratometric stability at the post-operative six-month period. The median time to reach\u00a0keratometric stability was 4 weeks (1 month), and the maximum time is six months.\nConclusion. Higher-grade pterygia required longer to achieve postoperative keratometric stability, informing optimal\u00a0timing of subsequent procedures. Biometry for cataract surgery is best performed \u22653 months after excision (\u22486\u00a0months for Grade 3) to ensure accurate IOL calculation, with further studies needed to evaluate varied cases and\u00a0long-term outcomes.<\/jats:p>","DOI":"10.47895\/amp.v60i14.12934","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T02:58:56Z","timestamp":1785812336000},"source":"Crossref","is-referenced-by-count":0,"title":["Time to Keratometric Stability after Pterygium Excision Surgery in a Tertiary Hospital in the Philippines"],"prefix":"10.47895","volume":"60","author":[{"given":"Anselme W.","family":"Ang, MD","sequence":"first","affiliation":[{"name":"Mariano Marcos Memorial Hospital and Medical Center, Ilocos Norte, Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilette Marie B.","family":"Canilao, MD","sequence":"additional","affiliation":[{"name":"Mariano Marcos Memorial Hospital and Medical Center, Ilocos Norte, Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer Joy","family":"Santos\u2013Rayos, MD","sequence":"additional","affiliation":[{"name":"Mariano Marcos Memorial Hospital and Medical Center, Ilocos Norte, Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Fe S.","family":"Navarrete, MD","sequence":"additional","affiliation":[{"name":"Mariano Marcos Memorial Hospital and Medical Center, Ilocos Norte, Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"27557","published-online":{"date-parts":[[2026,7,31]]},"container-title":["Acta Medica Philippina"],"original-title":[],"link":[{"URL":"https:\/\/actamedicaphilippina.upm.edu.ph\/index.php\/acta\/article\/download\/12934\/7212","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/actamedicaphilippina.upm.edu.ph\/index.php\/acta\/article\/download\/12934\/7212","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T02:58:57Z","timestamp":1785812337000},"score":1,"resource":{"primary":{"URL":"https:\/\/actamedicaphilippina.upm.edu.ph\/index.php\/acta\/article\/view\/12934"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,31]]},"references-count":0,"journal-issue":{"issue":"14","published-online":{"date-parts":[[2026,7,31]]}},"URL":"https:\/\/doi.org\/10.47895\/amp.v60i14.12934","relation":{},"ISSN":["2094-9278","0001-6071"],"issn-type":[{"value":"2094-9278","type":"electronic"},{"value":"0001-6071","type":"print"}],"subject":[],"published":{"date-parts":[[2026,7,31]]}}}
