“…Similar results have been observed in previous studies. 6,7 Decrease of luminance was related to deterioration of CS. 26,27 Pupil or pinhole size has a large effect on the optical transfer function of the eye, and if the pupil or pinhole size is fixed, transfer rate decreases more as frequency increases.…”

“…23 These effects of pinhole glasses can support presbyopia, and this concept led to the development of a small-aperture corneal inlay. [5][6][7] Image quality increased by a pinhole can be diminished when the level of illumination reaching the retina is attenuated. 24 In this situation, pinhole glasses with a series of equally sized, regularly placed pinholes are better than a single pinhole occluder.…”

“…19,26 The explantation rate in cases of visual dissatisfaction varies widely across series from 0% to 21%. 14,22,[27][28][29] One study concluded that after removal, corneal topography and aberrometry were not permanently affected with a return to preoperative corrected and uncorrected vision in the majority of cases. 30 Advances in the biocompatibility of materials and designs allowing for improved metabolic regulation have made modern inlays much safer than their precursors.…”

In refractive surgery, the use of intracorneal implants, including intracorneal ring segments (ICRS) and corneal inlays, offer the specific advantage of not removing corneal tissue. As such, they are removable and may preserve options for ametropia or presbyopia correction with current or future modalities. 1,2 However, there are unique intraoperative and postoperative complications that can occur with their implantation that need to be recognized and managed. The following review will focus on the incidence and management of complications from the use of intracorneal implants in refractive surgery. ' ICRS for Correction of MyopiaICRS are polymethylmethacrylate segments implanted in the deep corneal stroma to modify the corneal curvature based on their geometric profile and diameter. Although initially approved for low myopia in the United States in 1999, 2 the technology was soon after used for the treatment of keratoconus. 3 The creation of channels for the placement of ICRS can be performed either mechanically using semicircular dissectors or with a femtosecond laser. Although the femtosecond laser creates channels with a high degree of precision, no published studies have demonstrated higher complications or inferior refractive outcomes for myopia with mechanical channel creation. For the treatment of myopia, ICRS offer the advantage over ablational laser refractive surgery of sparing the visual axis with very low risk of central corneal haze or scarring, and the effects may be reversible with removal of the segments. 2,4,5 Although corneal excimer laser refractive surgery has largely replaced the use of ICRS for myopia due to the excellent outcomes, there may still be a role for ICRS for the treatment of low

“…The KAMRA ® inlay (AcuFocus Inc., Irvine, CA, USA), a small-aperture intra-corneal inlay medical device aiming at correcting presbyopia, can be monocularly implanted into a lamellar pocket in the nondominant eye of a patient. Its mechanism of action is to restrict unfocused peripheral light rays to provide increased depth of focus and an extended range of continuous vision expanding from near to far [8,9].…”
