Application of femtosecond laser in surgery of open trauma of the eyeball with intraocular foreign body

Rationale: open eye trauma with the presence of an intraocular foreign body continues to be among the leading causes of vision loss and disability globally. Objective: – to study the possibility of performing posterior femtocapsulorhexis in patients with open eyeball trauma and to evaluate its effectiveness in preserving the supporting function of the lens capsular bag during removal of an intraocular foreign body through the anterior chamber of the eye. Methods: in 2023-2024, 7 patients (7 eyes) were treated at the Kaluga branch of “Eye Microsurgery” with a diagnosis of open trauma to the eyeball with an intraocular foreign body. The age of patients ranged from 20 to 66 years. All patients underwent diagnostic examination. The patients were recommended surgical treatment in the following scope: phacoaspiration of the transparent lens (or phacoemulsification of traumatic cataract) with femtosecond laser accompaniment at the stage of posterior capsulorhexis + vitrectomy + removal of intraocular foreign body by a combined method + IOL implantation. Results: all surgical interventions were performed without intraoperative complications. In all patients, the intraocular foreign body was removed using a combined approach through the anterior chamber and corneoscleral tunnel incision. In all cases, the IOL was successfully implanted into the capsular bag. Conclusion: the developed technique for performing posterior femtocapsulorhexis in open eye trauma with an intraocular foreign body increases the functional and anatomical effectiveness of surgical treatment of patients with eyeball trauma during removal of an intraocular foreign body from the vitreous cavity through the anterior chamber.
