“…Guggenheim et al . also analysed symmetry in relation to the level of astigmatism, but according to their findings, there was no difference in symmetry between astigmatism less than and more than 1.00 D. We categorised astigmatism into three levels of mild, moderate, and high, which is clinically better and more common for research purposes . Considering this more logical categorisation and the larger sample size, our results may be more reliable.…”

“…This was lower than the 56.3% reported by Murphy et al ( 13 ). Patients’ age and pre-existing corneal astigmatism were found to be potential contributors to the reduced UCVA in several studies ( 3 , 17 – 18 ). Older patients especially those above the age of 65 years old have significantly poorer UCVA ( 3 , 18 ).…”

“…Older patients especially those above the age of 65 years old have significantly poorer UCVA ( 3 , 18 ). Furthermore, patients with pre-existing corneal astigmatism have perceived blurry vision post-operatively as little as 0.75 D astigmatism ( 17 ). Further study is required to identify factors that contribute towards the reduced UCVA in Hospital Keningau so that remedial measures can be taken.…”

Background: A good refractive outcome after cataract surgery indicates adequate clinical service provision. Precise immersion biometry is critical to achieve the desired refractive outcome. While the immersion biometry results are good in the tertiary settings, it is of interest to explore the refractive outcome of cataract surgeries in a rural facility using the same technique. Methods: A retrospective cross-sectional review was conducted on medical records of all cataract surgeries carried out in Hospital Keningau, Sabah. This study used all patients’ medical records who had been assessed using immersion biometry pre-operatively, underwent phacoemulsification cataract surgery besides attending a post-operative refraction session within 90 days from the operation date. Clinical details were recorded in the form of standard proformas and analysed. The refractive outcome was evaluated using spherical equivalence (SE) and bestcorrected visual acuity (BCVA). The percentage of cases with post-operative SE within ±1.00 diopter (D) and BCVA of ‘6/12 or better’ were determined. The association between demographic factors and surgical-related factors with post-operative SE was evaluated using Fisher’s exact test. Results: Of 140 cataract surgeries, 113 fulfilled the inclusion criteria. The average patient age was 66.3 (SD = 10.9) years old. The technique was proven to replicate a good outcome of 84.1% of cases with post-operative SE within ±1.00 D while 90.3% of the cases achieved BCVA of ‘6/12 or better’. Age and ethnicity were found to be associated with post-operative SE. Conclusion: The study proves the reproducibility of good refractive outcome in a rural facility using immersion biometry. The findings provide a benchmark for performance surveillance in rural facilities.
