Modified Technique for Scleral-Sutured Fixation with the Double Knots Technique for Posterior Chamber Intraocular Lens: Short-Term Observation

Figure 1

The process of transscleral-sutured IOL fixation. (a) Cow-hitch knots are created with the method that the long curved needle passes through the eyelet of one haptic of the IOL. (b) The curved needle was introduced through the corneal incision, docked into a 23-G needle introduced from the 2 o’clock and 8 o’clock scleral incision, and pulled out. (c) The first ball-shaped knot was created in 3-2-1 fashion. (d) The second ball-shaped knot was created in 3-2-2 fashion and tied about 3 mm away from the first knot. (e) The long needle with thread entered the other scleral lamina from the incision and sneaked 4-5 mm between the scleral layers. (f) The second thread knot was buried in the deep sclera. (g) The same procedures were performed for the opposite side and IOL centration adjusted. (h) The peripheral iris was excised at 1 o’clock with 23-gauge vitreoretinal surgery.
