I would also consider treating the patients glaucoma at this time with endoscopic cyclophotocoagulation. With this RGP contact lens in position VA was improved to 20/20. using balanced salt solution (Figure 4). It is feasible to correct ametropia with SMILE in patients with corectopia after intraocular lens implantation. Due to the mid-dilated peaked pupil at 10 o'clock position, there was an exposed implanted lens margin that permitted light to be refracted through the aphakic and pseudophakic portions simultaneously as shown in Figure Figure2.2. The ICC for the 7 inexperienced ophthalmologists regarding the grading of direction and centration of the pupil was 0.83 (95% confidence interval (CI), 0.74 to 0.90; p < .001) and 0.57 (95% CI, 0.43 to 0.72; p < .001), respectively. Surgery improves vision for 97% of people. Numerous reports on the use of the Nd:YAG laser to treat structures in the anterior segment have emphasized the need to use higher pulse energy for pupillary membranes, compared with the lower settings required for posterior capsulotomy. Thus, even though refractive error may be corrected with glasses or contact lenses, patients are often not happy with this result. Left eye visual status during the subsequent visits. Exchange is technically easiest to perform in the early post-operative period (within 4 months). I would engage the distal superior portion of the temporal haptic of the IOL with the Lester hook and gently pull the haptic inferiorly and anteriorly in hopes of disengaging it from the iris (with continued injection of the viscoelastic substance).
