Effect of defocus incorporated multiple segments (DIMS) spectacle lenses on myopia progression in children: a retrospective analysis in a German real-life clinical setting.

Objectives: This retrospective analysis evaluates the treatment success of "Defocus Incorporated Multiple Segments" (DIMS) spectacle lenses in a real-life clinical setting in Germany.

Materials And Methods: Axial length (AL) and objective refraction of 166 eyes treated with DIMS at baseline and 12-month follow-up were analyzed. Annual AL growth rate within the range of physiological growth rate was considered a successful treatment.

Customizing Clinical Outcomes with Implantation of Two Diffractive Trifocal IOLs of Identical Design but Differing Light Distributions to the Far, Intermediate and Near Foci.

Purpose: To evaluate clinical outcomes after bilateral or contralateral implantation of the Gemetric™ (G) and Gemetric™ Plus (GPlus) diffractive trifocal intraocular lenses (IOLs).

Methods: This was a prospective, randomized, multi-center open-label study comparing clinical results and subjective patient responses around 6 months after implantation of the study lenses (toric and non-toric) in three different groups (bilateral G, bilateral GPlus and contralateral G/GPlus implantation). Results included the manifest refraction, uncorrected and distance corrected monocular and binocular visual acuity (VA) at distance, intermediate and near; the defocus curve; contrast sensitivity; and patient reported outcomes regarding spectacle independence, satisfaction and visual disturbances.

Contrast Adaptation in Pseudophakic Patients with Macular Disorders.

Purpose: To learn whether contrast adaptation, induced by positive spherical defocus, is compromised by macular disorders such as age-related macular degeneration (AMD) or epiretinal membranes (ERM) and to gain further insight in the functionality of the pathological macula and the level of "functional reserve" often postulated for the indication of presbyopia correcting IOLs.

Methods: In a pilot study, patients with macular disorders, AMD and ERM, ( = 10) and healthy volunteers ( = 10) were tested to quantify contrast adaption after +4 D defocus for 10 min, by performing an interocular contrast matching task. Subjects manually adjusted the perceived contrast of the test patch as seen by the test eye to match to the contrast of a target patch with a fixed Michelson contrast of 0.

A Comparison of Optical Biometers Used in Children for Myopia Control.

Purpose: To assess the reproducibility (i.e., inter-device reliability) of the biometers Topcon MYAH, Oculus Myopia Master, and Haag-Streit Lenstar LS900 with the Carl Zeiss IOLMaster 700 and the intra-subject repeatability in myopic children in order to reliably detect axial growth for myopia management.

[Post-SMILE-What myopes know about their secondary emmetropic eyes].

Background: Small incision lenticule extraction (SMILE) is popular among young myopic adults for long-term correction of myopia; however, the excessive axial lengths of myopic eyes and the associated risks for more serious eye diseases later on remain with surgical correction of the refractive error. These risks are greater the higher the myopia is. Are patients well informed about this and to what extent does further eye growth occur even after SMILE?

Material And Methods: Myopic young adults who underwent binocular SMILE before 2019 were given the opportunity to have their eyes examined at a follow-up visit (biometry using IOL-Master 700 [Zeiss, Oberkochen, Germany], subjective refraction, examination of the anterior and posterior segments of the eye using the slit lamp) and to participate in a survey.
