Purpose:
This paper is a case report of the use of femtosecond laser for cataract surgery to implant an implantable miniature telescope for a patient with large central areas of geographic atrophy.
Observations:
On postoperative day 1 the patient's uncorrected visual acuity at near was 20/50. The cornea was clear and the patient reported no problem with navigation without occupational therapy training.
Conclusions And Importance:
To our knowledge and confirmed by the manufacturer of the implantable miniature telescope this is the first case ever reported of a patient who has undergone femtosecond laser cataract surgery with corneal astigmatism correction and implantation of the implantable miniature telescope. This is also the first case report of the preoperative use of microperimetry and visual electrophysiology to evaluate a patient's postoperative potential visual acuity. The success of the procedure illustrated the importance of meticulous preoperative planning, the combined use of state-of-the-art technologies and the seamless teamwork in order to achieve the best clinical outcome for patients who undergo implantation of the implantable miniature telescope.
