We found that the use of a femtosecond laser for DALK provides in-depth air separation and enhances the frequency of formation of a «Big bubble» air bubble, thus reducing the risk of conversion to a penetrating procedure.deep anterior lamellar keratoplastyfemtosecond laser-assisted surgeryглубокая передняя послойная кератопластикафемтолазерное сопровождение[Малюгин Б.Э., Паштаев А.Н., Елаков Ю.Н. и др.
