A decade of intracapsular cataract extraction: Clinical profile and visual outcomes at Hospital Melaka, Malaysia.

Introduction: Cataract is a leading cause of visual impairment globally and in Malaysia, with surgery being the definitive treatment. While intracapsular cataract extraction (ICCE) is now less commonly performed due to advancements in surgical techniques, it remains essential in specific cases, such as those with weak zonular support. This study aims to evaluate the incidence, clinical profiles, and visual outcomes of patients who underwent ICCE, with or without intraocular lens (IOL) implantation, at Hospital Melaka, Malaysia, over the past decade.

Materials and methods: A retrospective review was conducted on patients who underwent ICCE at Hospital Melaka, Malaysia, from January 2014 to December 2023.

Results: A total of 143 ICCE surgeries were performed on 135 patients. Most patients were male (n=88, 65.2%), with females comprising 34.8% (n=47). Most surgeries were performed on patients aged 60-69 years (n=48, 35.5%), followed by those aged 50-59 years (n=31, 23.0%) and 70-79 years (n=28, 20.7%). Incidence was lower among patients below 50 years and above 80 years. In terms of ethnicity, the highest incidence was among Malays (n=77, 57.0%), followed by Chinese (n=42, 31.1%) and Indians (n=15, 11.1%). The leading cause of ICCE was senile cataract with weak zonular support (n=58, 40.6%), followed by trauma (n=33, 23.1%), intraoperative complications (n=30, 21.0%), congenital cataracts (n=14, 9.8%), pseudoexfoliation (n=4, 2.8%), and lens-induced glaucoma (n=4, 2.8%). Post-surgery, 76 patients (53.1%) were left aphakic. Among those receiving IOL implants, 21.0% (n=30) had anterior chamber IOL, 14.7% (n=21) received an iris-claw IOL, and 11.2% (n=16) had a scleral-fixated IOL. Twelve weeks after IOL implantation, 60.9% (n=39) achieved good visual acuity of 6/12 or better, while 17.2% (n=11) had moderate vision (6/18 to 6/36), and 21.9% (n=14) had poor vision (worse than 6/60).

Conclusion: The incidence of ICCE was low, accounting for only 0.66% of the 21,596 cataract surgeries performed at Hospital Melaka, Malaysia, during the study period. The primary indication was senile cataracts with weak zonular support. Most patients achieved favourable visual outcomes at 12 weeks postsurgery following IOL implantation, with the iris-claw IOL showing superior postoperative visual results compared to other IOL types.
