Purpose

To assess contrast sensitivity of central and peripheral vision with a newly developed, internet-based Spaeth/Richman Contrast Sensitivity (SPARCS) test in subjects who underwent myopic photorefractive keratectomy (PRK) or femtosecond laser in situ keratomileusis (femto-LASIK) refractive surgery in comparison with controls.

Setting

401 General Military Hospital of Athens

Methods

In a retrospective study a total of 186 eyes from 93 subjects were analyzed: 62 eyes from 31 subjects for each of the three groups under comparison. Controls and patients that underwent a refractive surgery procedure and controls were evaluated using the SPARCS test. SPARCS scores were obtained for central and four peripheral areas (right upper (RUQ), right lower (RLQ), left upper (LUQ), and left lower quadrants (LLQ)). Total, central and peripheral SPARCS scores in subjects with refractive surgery were compared with controls adjusting for possible confounders. Multivariate and mixed linear regression models were used.

Results

Subjects having PRK had a lower score in all categories compared with the control group: by 5.9 points (95% CI, -9 to -2.8) in the total score, by 1.6 points (95% CI, -3 to -0.3) in the central and by 5.5 points (95% CI, -9.4 to -1.6) in the peripheral score. Patients after femto-LASIK had non-statistically significant lower scores than the control group.

Conclusion

Photorefractive keratectomy causes a decrease in central and peripheral contrast sensitivity.
