Introduction: Strabismus is a condition in which the eyes are not properly aligned with each other. It may be accompanied by abnormal motility of one or both eyes with multifactorial factors including both genetic and environmental. A surgical treatment is one of the options.

Objective: To determine the outcome of surgery treatment of strabismus patients.

Methods: It was a cross sectional study conducted in Department of Ophthalmology at Children’s surgical center that located in Kien Khleing National Rehabilitation Center, Phnom Penh, Cambodia from January 2009 to October 2014 with the sample size of 269 cases. All surgeries were conducted under general anesthesia, following routine pediatric techniques. Horizontal squint surgery was performed as the first surgery, using standard surgical dosage tables without modification.

Results: There were totally 269 strabismus cases consisting 34% male and 66% female found in this study. 91.82% of the cases were seen in the age group from 0-9 years. 59% of cases were considered as congenital (onset before 6 months old) against 41% of acquired strabismus (onset after 6 months old). 92% of the cases were treated by horizontal surgery whereas other 4% were vertical squint (2%) and torsional (2%). There were 68% of cases had orthotropia (fully corrected), 24% had undercorrected esotropia, 6% had undercorrected exotropia and 2% had overcorrected. The Majority of cases had successful surgery treatment without complication. However, there were some complication seen such as 1% of diplopia, 2% of re-operation and 0.37% of scleral perforation.      

Conclusion: In conclusion to this study, we found that strabismus was affected in female more than male. Children from 0-9 years old are the most commonly seen in term of age. There was highest number of cases recorded from Kampong Cham province than other provinces. There were 96% of had surgery treatment and got better outcome and the complication was noted in just 3.5% of cases.
