Cataract Extraction Surgery After Kamra Inlay Implantation: A Four-Patient Case Series

the purpose of this study is to study the safety and visual outcomes of cataract surgery in patients with prior KAMRA inlay implantation, with emphasis on the challenges posed by altered corneal optics in achieving accurate intraocular lens (IOL) power calculation and successful IOL implantation.

The case series was conducted at Advanced Eye Care Hospital, where all procedures were performed by the same experienced surgeon in a controlled clinical environment.

Four patients with a history of KAMRA inlay implantation who subsequently developed visually significant cataracts underwent standard phacoemulsification cataract surgery. Preoperative optical biometry was carefully performed considering the inlay’s impact, and IOL power was determined using established IOL power calculation formulae such as the Haigis and SRK/T. During surgery, standard phaco machine settings were utilized while retaining the inlay in situ, ensuring continuity of near vision benefits.

All patients achieved favorable postoperative visual acuity outcomes with minimal complications. The surgical approach, which incorporated precise IOL power calculation and optimization of phaco machine settings, facilitated successful cataract removal and IOL implantation. Retaining the KAMRA inlay during surgery allowed patients to preserve enhanced near vision, demonstrating that careful preoperative planning and technique adaptation can overcome the challenges associated with altered corneal optics.

Cataract surgery in patients with prior KAMRA inlay implantation can be performed safely and effectively. Accurate IOL power determination using appropriate formulae and optimized surgical parameters are crucial in maintaining visual benefits. Further research with a larger cohort is warranted to substantiate these findings and refine surgical protocols.
