摘要: Abstract Objective To evaluate change in axial length measurement after successful glaucoma filtering surgery. Design Retrospective consecutive case series. Participants Sixty-two patients with phakia who underwent primary trabeculectomy. Intervention The A-scan biometry of ocular before and Main outcome measures Changes trabeculectomy were analyzed. Results mean decrease was 0.423 mm (range, −2.8 to +0.5 mm). Regression analysis yielded a statistically significant association between age ( P = 0.0001) post-trabeculectomy intraocular pressure greater than 30 mmHg 0.01). Analysis variance revealed use antimetabolite 0.005). Pseudophakic measurements increased an average 0.275 compared the cataract Conclusions Axial decreased 32 62 eyes initial A may have influence on lens calculations. Therefore, authors recommend that be obtained phakic reduce risk inaccurate power calculation based measurements.
