Of these, 161 (55.1%) were from public centres, 131 (44.9%) from private centres and 8 cases could not be identified. In most centres, biometry was performed by an optometrist (43.5%), followed by nurses (28.5%) and ophthalmologists (27.1%). The most frequent biometer was the IOLMaster 700 (89 centres), followed by the IOLMaster 500 (76 centres). For spherical power calculation Barrett Universal II (58.3%) was the preferred formula, followed by SRK\/T (22.7%). For toric IOL calculation, Barrett toric was the most used formula (71.7%), followed by Kane (9.0%), and for postrefractive surgery cases it was Barrett true K (38.3%), followed by the ASCRS calculator (28.7%). Half of the respondents (53.3%) expressed a need for further training on biometry and IOL calculation<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n                    <jats:p>This survey updates the state of biometry and IOL calculation in our country, highlighting areas for improvement and promoting evidence-based practices.
