Abstract: The present disclosure generally relates to devices for ophthalmic procedures, and more particularly, to apparatus for performing subretinal injections and methods of use thereof. In some embodiments, the apparatus includes an injection needle having a proximal end and a distal end, the distal end configured to be insertable into the subretinal space at a position on a surface of a retina. The apparatus may further include an inserter device removably coupled to the injection needle and a tubing having a distal end coupled to the proximal end of the injection needle and a proximal end coupled to a fluid source. The tubing may have a first lumen and a second lumen, wherein the tubing is disposed through the inserter device. The apparatus may further include a stabilizer configured to immobilize the injection needle at the position on the surface of the retina and a fluid source. The fluid source may include both a first fluid reservoir containing a non-treatment solution and a second fluid reservoir containing a treatment solution. The fluid source may be configured to provide the non-treatment solution from the first fluid reservoir to the subretinal space via the first lumen. The fluid source may be further configured to provide the treatment solution from the second fluid reservoir into the subretinal space via the second lumen.
