MANAGEMENT OF TRAUMATIC APHAKIA WITH SECONDARY INTRAOCULAR LENS IMPLANTATION USING YAMANE TECHNIQUE IN A NATIONAL REFERENCE CENTER

To describe the visual outcome and complications in patients with traumatic aphakia managed with secondary intraocular lens implantation with Yamane technique.

Ocular trauma can cause a host of complications including traumatic aphakia, this is defined as the loss of the lens due to severe ocular trauma, open or closed. Although it is an injury that is usually associated with other injuries that require a much more urgent resolution, it is important to treat it due to the improvement in the visual acuity and the quality of life of patients. Currently there are different options to treat it, in this summary we describe a series of cases of aphakia treated with the Yamane technique, in a national ocular trauma center with a high volume of patients.

A series of cases of patients with traumatic aphakia and managed with a secondary implant with Yamane technique were carried out in the national ocular trauma unit of the Hospital del Salvador, during the years 2020 to 2022.

All patients with aphakia due to ocular trauma managed with this technique were included, and patients managed with other techniques or with modifications of the original technique were excluded.

The data was tabulated and a descriptive statistical analysis of the results was performed.

During the period studied, 61 secondary intraocular lens implantations were performed with Yamane technique. Of which 79% correspond to men and 21% to women. The average age was 53 years, with an age range of 7 to 79 years.

Regarding the mechanism of trauma, 79% were blunt and 21% were penetrating. Of the patients studied, 87% had LogMAR visual acuity 0.5 or worse, 60.7% without chart  vision. In relation to the visual results, 46% achieved visions greater than LogMAR 0.5, 34% visions less than LogMAR 0.5 and only 7% did not achieve chart vision.

Finally, there were intraoperative complications in up to 23% of the cases, which were mainly haptic breaks, but their incidence was lower when the surgery was performed by a “Senior” staff.

Secondary intraocular lens implantation with Yamane technique is an efficient technique in the management of traumatic aphakia, with excellent visual results considering the context of patients with severe ocular trauma.
