AIM

To compare the visual outcomes between bilateral implantation of Tecnis ZXR00 extended depth-of-focus (EDOF) intraocular lenses (IOLs) and mixed implantation of Tecnis ZXR00 (EDOF) with Tecnis ZMB00 (bifocal) IOLs.

METHODS

This postoperative cross-sectional study enrolled patients who underwent phacoemulsification combined with IOL implantation. Patients were divided into two groups: the bilateral ZXR00 group (ZXR00-only group) and the mixed IOL group (ZXR00+ZMB00 group). Primary outcome measures included uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and distance-corrected near visual acuity (UNVA, DCNVA), uncorrected and distance-corrected intermediate visual acuity (UIVA, DCIVA), and defocus curves. Secondary outcome measures were visual quality, spectacle independence, patient satisfaction, photic phenomena, and stereopsis.

RESULTS

A total of 47 patients (94 eyes) were included, with 26 patients (11 males, 15 females) in the ZXR00-only group (mean age: 62.73±7.24y) and 21 patients (7 males, 14 females) in the mixed group (mean age: 65.71±9.16y). There was no statistically significant difference in age between the two groups (P=0.218). The mixed group showed significantly better binocular DCNVA compared to the ZXR00-only group (P=0.002). Defocus curve analysis revealed that the mixed group exhibited superior performance at −2.5 to −4.0 D but inferior performance at −0.5 and −1.5 D. Near stereoacuity was significantly poorer in the mixed group (Randot: 5.589±0.744 vs 6.240±0.394 ln arcsec; Contour: 4.966±0.973 vs 5.740±0.833 ln arcsec; both P<0.01). Both groups achieved high levels of spectacle independence and patient satisfaction, with no significant differences in photic phenomena or questionnaire scores.

CONCLUSION

Mixed implantation of EDOF and bifocal IOLs improve near visual acuity but may compromise near stereopsis. This approach provides a viable option for patients prioritizing near vision; however, caution is recommended for individuals requiring fine stereoscopic vision for daily or professional tasks.

AIM

To evaluate and compare alterations in the effective lens position (ELP) and refractive outcomes among three distinct intraocular lens (IOL) types.

METHODS

Patients with cataracts were enrolled and allocated to 3 groups: Group A (implanted with the SN6CWS), Group B (implanted with the MI60), and Group C (implanted with the Aspira-aA). ELP measurements were obtained with swept-source optical coherence tomography (SS-OCT) at 1d, 1wk, 1mo, and 3mo postoperatively. Subjective refraction assessments were conducted at 1wk, 1mo, and 3mo following surgery.

RESULTS

The study included 189 eyes of 150 cataract patients (66 males). There were 77 eyes in Group A, 55 eyes in Group B, and 57 eyes in Group C. The root mean square of the ELP (ELPRMS) within the initial 3mo was significantly lower for Group A than for Groups B and C. Refractive changes within Group A were not significant across the time points of 1wk, 1mo, and 3mo. Conversely, both Group B and Group C demonstrated statistically significant shifts toward hyperopia from 1wk to 3mo postsurgery.

CONCLUSION

Among the three IOLs examined, the SN6CWS IOL showes the greatest stability during the first 3mo postoperatively. Between 1wk and 3mo after surgery, notable hyperopic shifts are evident in eyes implanted with the MI60 and Aspira-aA IOLs, whereas refractive outcomes remain relatively constant in eyes implanted with SN6CWS IOLs.

AIM

To find out intraoperative and postoperative outcomes of congenital cataract surgery in eyes with microcornea.

METHODS

This retrospective consecutive case series study compared outcomes after congenital cataract surgery in eyes with/without microcornea. Infants (<1 year old) who underwent lensectomy surgery left aphakic were included. Microphthalmos was defined as an eye that has a horizontal corneal diameter less than or equal to 9.0 mm.

RESULTS

There were 40 infants (54 eyes) in the microcornea group and 58 (87 eyes) in the control group. The two groups were age- and sex-matched. The microcornea group showed significantly smaller corneal diameter (P<0.001), steeper corneal keratometry (P=0.001), thinner lens thickness (P<0.001), and shorter axial length (AL, P<0.001). And microcornea increased the incidence of poor pupil dilation (P<0.01). The two groups showed no significant differences in postoperative intraocular pressure (IOP), best-corrected visual acuity, central corneal thickness (CCT), AL, and the incidence of strabismus and nystagmus at the last follow-up.

CONCLUSION

Although microcornea have different features from normal ones, the one-year follow-up after surgery has shown that early surgical intervention for congenital cataracts in eyes with microcornea can result in favourable outcomes with an acceptable rate of postoperative complications. Regular follow-up and timely management of postoperative complications are crucial for successful outcomes.
