—We thank Dr Shin for his comments regarding our new surgical instrument for placement of transscleral iris fixation sutures. We agree that a simple hypodermic needle is effective in situations where our instrument is unavailable,1,2 but we think that our specially designed needle facilitates the rapid, atraumatic suture placement essential for iris fixation and for transscleral suture placement during posterior chamber intraocular lens fixation.3 We also wish to note that production of the transscleral fixation needle has recently been retooled, which has markedly enhanced the sharpness of the instrument.
