The study was<br>carried out at the Section of Ophthalmology, Department of Surgery, Aga Khan<br>University Hospital, Karachi. Eyes scheduled to undergo phacoemulsification<br>during December 2011 – March 2012 were eligible to be included. Eyes with<br>corneal degenerations, dystrophies or high pre-op astigmatism were excluded. A<br>structured proforma was used to collect data on sociodemographics, comorbids,<br>visual acuity, and CCT before surgery and 1 day, 1 week and 1 month after<br>surgery. Changes in the mean CCT over time were measured using repeated<br>measures Analysis of Variance (ANOVA) was done.<br>Results: Eighty one eyes were included in the study. The mean (±SD) age of<br>the participants was 58.30 (± 10.04) years. The majority of them (58.0%) were<br>women. Sixty two (76.5%) eyes completed the last follow-up and were included<br>in the final analysis. The mean CCT was 542.81 ± 34.85 mm before surgery<br>which markedly increased to 595.27 ± 43.78 mm 24 hours after surgery, but<br>decreased to 565.82 ± 38.30 at one week, and returned to normal baseline<br>values (544.42 ± 28.95) in almost all operated eyes in 1 month time. There was<br>no statistically significant difference in the mean CCT before surgery and at 1<br>month (p=0.685).<br>Conclusion: The mean CCT substantially increasing after post-operative<br>uneventful cataract surgery but returns to normal baseline values in almost all<br>operated eyes in 1 month time. IOP measured during this period may be falsely<br>higher than the true values due to increased CCT.<br>Key words: central corneal thickness, phacoemulsification, cataract surgery</p>}, number={2}, journal={Pakistan Journal of Ophthalmology}, author={Wajiha Koomal, Khabir Ahmad, Tanveer Anjum Chaudhry, Muhammad Hamza,}, year={2015}, month={Jun.} }
