Summary
This study found that pseudophakic eyes (post-cataract surgery with intraocular lens implants) show persistently worse tear film stability and corneal staining compared to contralateral phakic eyes even years after surgery. These findings suggest that long-term ocular surface monitoring is warranted for patients with intraocular lens implants, which is relevant to lighting design contexts where visual comfort and ocular health intersect.
Key Findings
- Tear break-up time (TBUT) was significantly shorter in pseudophakic eyes (3.8 ± 1.9 s) compared to contralateral phakic eyes (4.4 ± 1.9 s), p < 0.001.
- Keratoconjunctival staining scores were significantly higher in pseudophakic eyes (0.22 ± 0.56) vs. phakic eyes (0.11 ± 0.38), p = 0.02, indicating greater corneal surface damage.
- Ocular surface deterioration persisted over a mean postoperative period of 4.6 ± 4.4 years (range 1–20 years), suggesting chronic rather than transient surgical effects.
- Intraocular pressure and refractive outcomes did not differ significantly between eyes, isolating the ocular surface as the primary area of concern.
