This technique of performing pinhole pupilloplasty helps filter the straylight from the periphery of the cornea in cases with higher-order corneal aberrations. The pinhole effect blocks distorted and unfocused light rays and isolates more focused central and paracentral rays through the central aperture, thereby reducing aberrations of the optical system as a whole and enhancing visual acuity and its image quality.

The authors developed a new surgical technique of retropupillary implantation of an iris-claw intraocular lens (RP-ICIOL). RP-ICIOL is an alternative surgical option to the scleral-fixation technique for the treatment of aphakia without capsular support. Several studies have shown that RP-ICIOL is efficient and safe. However, although it is easier to perform than scleral fixation, it presents some critical issues related to the enclavation procedure. The success of the correct enclavation without excessive surgical manipulations, with subsequent pigment dispersion and without pupil distortion, is highly related to the surgical skills of the individual surgeon...

We describe a technique for repositioning an encapsulated, posteriorly dislocated silicone plate-haptic toric intraocular lens (IOL) while preventing further dislocation into the vitreous cavity. Sutures of 10-0 polypropylene were used to ensure safe retrieval of the dislocated IOL. An anterior vitrectomy was then performed to remove the contracted capsular bag around the IOL. The IOL fixation hole was temporarily externalized to allow quick and secure IOL fixation, eliminating the risk for losing the slippery silicone IOL into the vitreous cavity...

Small-incision lenticule extraction (SMILE) was performed in a patient with high astigmatism and nystagmus. The patient presented for a refractive surgery evaluation with a manifest refraction of -0.50 -6.00 × 137 (20/40-1 ) in the right eye and -2.25 -2.25 × 30 (20/40-1 ) in the left eye. The patient was deemed suitable for corneal laser refractive surgery. Consideration was given to SMILE, laser in situ keratomileusis, and photorefractive keratectomy. It was decided SMILE was the best option given that the refractive portion of the procedure is performed while the cornea is immobilized by suction...

The implantable collamer lens (ICL) is a widely used posterior chamber phakic intraocular lens that achieves excellent refractive results. Nonetheless, serious postoperative complications related to inadequate vault have been previously reported. Therefore, lens exchange is advised when the vault is out of the recommended ranges. This article presents a case with persistent low vault after lens exchange in which no clinical evidence of crystalline lens opacity or decrease in uncorrected distance visual acuity has been identified during the 6-year clinical follow-up performed to date...
