“…With 4.25 D of corneal cylinder and an UNVA of 6/19 postoperatively, the patient was 'delighted' with the functional range of vision provided in their work as a truck driver. The advantage of the pin hole design in the treatment of irregular corneal astigmatism is also well documented with the XtraFocus pin hole IOL (Morcher, Stuttgart, Germany) [18][19][20][21]. The XtraFocus implant is a black, hydrophobic acrylic sulcus IOL that can be used in pseudophakic eyes, masks a greater area which may help with pupil abnormalities such as Aniridia and is translucent to infrared imaging.…”

Background To investigate visual outcomes following cataract surgery in patients who were implanted monocularly with an extended range of focus IC-8 IOL. Methods A multicentre, non-randomised, retrospective case series of 126 consecutive patients implanted with the IC-8 IOL. Data were collected and pooled from six centres across Australia. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 80 cm and uncorrected near visual acuity (UNVA) at 40 cm were measured in eyes implanted with the IC-8 IOL. Adverse events, spectacle independence, visual symptoms and patient satisfaction were assessed at final follow-up. Results Over 90% of the patients without pre-existing ocular pathology (n = 109) achieved UDVA, UIVA and UNVA of 6/ 12 or better in the IC-8 eye. Binocularly, in this group, 98% achieved UDVA of 6/9, 94% UIVA of 6/12 and 91% UNVA of 6/12 or better. By final follow-up, over 50% of patients reported complete spectacle independence for distance, intermediate and near visual activity, with the remainder only using spectacles for specific tasks such as near-vision hobbies and reading in dim light. Conclusions The IC-8 IOL is capable of providing extended depth of focus following cataract surgery. It allows complete spectacle independence in more than half of the patients implanted with the IC-8 IOL.

“…The pinhole effect has been already exploited by the add-on XtraFocus lens (Morcher), a total black IOL for sulcus implantation, specifically designed for cases with corneal irregularities. [11][12][13] Compared to the XtraFocus lens, which is an add-on lens without optical power, the IC-8 has optical power and can be placed directly in the capsular bag during the cataract surgery, with a 1.36 mm central aperture and a non-diffractive 3.23 mm diameter opaque mask that allows the possibility of studying the retina, and also performing retinal surgery.…”

Purpose: Corneal irregularities can lead to high order aberrations (HOAs) and may influence the outcomes in terms of intraocular lens (IOL) selection and visual acuity assessment. The aim of this study was to evaluate the visual acuity and satisfaction after IC-8 implants in patients characterized by corneal irregularities and HOAs who could not undergo refractive surgery due to the poor residual thickness of the cornea or other conditions such as astigmatism secondary to previous radial keratotomy. Methods: This descriptive, retrospective cohort study was conducted on nine eyes in six patients affected by corneal irregularities and HOAs who had undergone IC-8 IOL implantation. The primary endpoint was the best-corrected visual acuity (BCVA), the subjective visual function, and the visual field. Results: Nine eyes of six patients (three bilateral implantation) were enrolled. For each patient, BCVA, vision, and lifestyle quality were evaluated. In all patients, we noticed an improvement in all parameters without visual field defects. Conclusion: Our work encourages the use of the IC8 lens to improve visual acuity in patients with irregular corneas and HOAs who cannot be treated with customized refractive surgery. Patients experience a subjective improvement of their quality of vision and also more self-confidence in their daily life. IC-8 lenses do not interfere with the visualization of retinal fundus and there is no impairment of the visual field detected by patients.

“…Small-aperture IOLs have been designed to address cases with irregular corneal aberrations and have been documented to enhance the functional vision and impart extended depth of focus. [1][2][3] These IOLs can be placed intraocularly; however, their availability is often an issue in many countries. Under such circumstances, PPP can be performed, and the benefits of pinhole optics can be availed.…”

“…Principles of small-aperture optics can be applied to cases with HOAs, which are refractory to other forms of currently available treatment. [2][3][4][5] The placement of an IC-8 IOL (Acufocus, Inc.) in post-RK case has been demonstrated to help achieve spectacle independence at distance, intermediate, and near. 1 In this study, we describe a safe and an effective technique of performing pinhole pupilloplasty (PPP) with single-pass 4-throw (SFT) method in the setting of previous RK using Purkinje 1 (P1) image as the marker for centration.…”

The multiple radial stromal deep corneal incisions placed in radial keratotomy (RK) lead to higher-order aberrations and pose a surgical challenge to performing any further corrective procedure on the cornea because of fear of inducing an incisional dehiscence. A method to perform pinhole pupilloplasty (PPP) in the setting of previous RK is presented. Application of pinhole optics by performing PPP leads to significant improvement in image quality and helps to optimize visual potential in post-RK cases.
