    Introduction Topical corticosteroids are routinely used after cataract surgery to decrease inflammation, relieve pain, and improve visual outcomes. However, they are known to have significant side effects, whether topically or systemically administered. Not much is known about the incidence of Steroid-Induced Ocular Hypertension (SiOH) in adult Ghanaians undergoing cataract surgery. Considering the immense negative impact visual impairment has on the quality of life of those affected, it is imperative to know the incidence of SiOH in the Ghanaian population. This would help in outlining preventive measures for potential ocular complications among patients undergoing cataract surgery. General Aim To determine the effect of steroid eye drops on intraocular pressure in patients post-cataract surgery and its associated risk factors. Methods This is a prospective cohort study of the effect of steroid eyedrops in patients post-cataract surgery at Korle Bu Teaching Hospital and Emmanuel Eye Centre. Patients undergoing cataract surgery were recruited into the study after informed consent. Demographic information, history and findings from ocular examinations were documented using a structured questionnaire. Baseline intraocular pressures were recorded. Post-operative intraocular pressures were measured on day one, weeks one, five and thirteen after surgery. Continuous numerical data were summarized as mean and Standard deviation (SD) and categorical data as percentages (%). Mean change in intraocular pressure from baseline was computed. Risk factors for SiOH were analysed using a Binary Logistic Regression Model and presented as Odds ratios and 95% Confidence Intervals. Kaplan-Meier survival function was used in calculating the average time (days) to develop SiOH among study participants. P-values less than 0.05 were considered statistically significant. Results A total of 124 patients participated in this study with a mean age of 66.1±13.6 years. Majority 75 (60.0 %) of the study participants were females. The overall mean pre-operative intra ocular pressure (IOP)in the study eyes was 17.8±4.4 mmHg with a 5.3% increase in IOP from baseline which was not statistically significant (p = 0.061). The incidence of SiOH in the study was 29% on post-operative day one and reduced to 1.6% at 13 weeks. In a univariate and multivariate analysis, there were no risk factors associated with the development of SiOH . A sub analysis of the ocular responses however picked up age as a risk factor for responding to the use of topical steroids. Participants aged 70 years and above were more likely to respond to the use of topical steroids after cataract surgery though this did not translate to a significant likelihood of developing SiOH in this cohort of patients undergoing cataract surgery. From Kaplan-Meier analysis, the overall mean time (days) to develop SiOH among the study participants was 55.3 days (95% CI= 47.3 – 63.3 days). Conclusion SiOH post-cataract surgery is a common complication in this study cohort with an incidence of 36.3 %; most of which (29%) occurred within the first month post-operation. There were no risk factors associated with the development of SiOH in this study. Patients undergoing cataract surgery should have their IOP monitored closely during their early postoperative visits to prevent ocular complications associated with prolonged raised IOP.
