Persistent blurred vision, poor contrast and ghosting at all distances after RayOne Galaxy Toric IOL — little improvement with refraction

TL;DR

I am a 34-year-old male. I had left-eye cataract surgery on April 13, 2026, with implantation of a RayOne Galaxy Toric IOL. At the time of writing on August 16, 2026, I am only about four months post-op. Since the first postoperative day, the eye has never produced a genuinely sharp or comfortable image.

• Distance vision is continuously blurred, low-contrast and smeared. Refraction improves it only slightly.
• Intermediate vision is poor. I can sometimes barely recognize or read text, often partly by guessing, but I would not call it usable.
• Without optical correction, normal-sized phone text is completely unreadable and not recognizable as individual letters; it appears blurred out.
• During my examination on August 15, 2026, the doctor tested my near vision using that day's correction (plano/−1.00 × 170) plus approximately +1.75 to +2.00 D ADD. Near text was then clear and comfortable.
• Letters have ghost images or light streaks, and vision feels like looking through a thin transparent film.
• Blinking and artificial tears do not meaningfully change the image.
• My right eye has its natural lens and sees 20/20 without correction.

Depending on the hospital, the left eye has been recorded between 0.4 and 0.7 with correction. The 0.7 result involved recognizing blurred letters partly by guessing; functionally, the image feels closer to approximately 0.5 and is much less comfortable than 0.7 suggests.

After visiting three hospitals, I still do not have a root-cause explanation. The possibilities I am considering include IOL tilt/decentration or another internal optical problem; clinically significant vitreous scatter, although I currently think this is less likely; or an inaccurate IOL power/toric correction, although this is unconfirmed because residual refractive astigmatism has generally measured only about 0.5–1.0 D depending on the examination. I currently consider the cornea less likely because the latest map was described by the doctor as fairly regular and symmetric without an obvious focal hot spot. I understand that map colors depend on the display scale and do not completely exclude a corneal contribution.

My main questions are:

1. Has anyone experienced a similar problem after an EDOF toric IOL? What was eventually found, and how was it managed?
2. Based on the symptoms and measurements below, what hypotheses would you consider in my case?
3. If you have seen a similar case, which specialist or examination actually helped identify the root cause?

Surgery on April 13, 2026, IOL and preoperative baseline — Hospital A

Hospital A performed my surgery on April 13, 2026, and holds the preoperative records. At the time of writing on August 16, 2026, I am only about four months post-op.

The implanted IOL is:

• RayOne Galaxy Toric, model RAO615X
• Spherical equivalent: +17.00 D
• Sphere: +15.87 D
• Cylinder at the IOL plane: +2.25 D
• Manufacturer-listed near add: +3.00 D
• Manufacturer-listed intermediate add: +1.50 D
• Optic diameter: 6.0 mm
• Target refraction: plano

The following measurements were taken with a Heidelberg Engineering ANTERION on March 14, 2026. These were obtained approximately one month before surgery; March 14 was not the surgery date:

• Axial length: 25.06 mm
• Total corneal astigmatism: 2.53 D at 94°
• Corneal HOA RMS at 5 mm: 0.22 µm, almost identical to the right eye at 0.21 µm
• Spherical aberration: 0.07 µm
• Pupil diameter: 5.2 mm
• Central corneal thickness: 513 µm

The preoperative cornea therefore appeared relatively regular. Multiple IOL formulas converged around +17.00 D for a plano target, so a major spherical IOL power error seems unlikely.

Latest examinations

Hospital C — August 7, 2026

A ZEISS VISUREF autorefractor/keratometer measured −0.25/−0.50 × 160, with approximately 2.25 D of corneal astigmatism. Subjective testing showed 20/40 both uncorrected and corrected; the record from this hospital listed a +1.75 D near ADD. Posterior OCT/RNFL and fundus examination found no explanatory macular or optic-disc lesion. B-scan ultrasound showed vitreous opacity without retinal/choroidal detachment.

The doctor said that nothing further could be done or offered. However, this visit did not include corneal tomography, whole-eye/internal aberrometry, quantitative IOL tilt/decentration analysis, retroillumination, contrast-sensitivity or straylight testing. My personal impression, which may be wrong, is that the hospital preferred not to pursue riskier intervention; I do not think the performed tests established that no treatable cause exists.

Hospital B — August 14, 2026

An OCULUS Pentacam showed regular corneal astigmatism of 2.4 D at 84.4° and a thinnest point of approximately 515 µm. Clinical testing showed 0.2 uncorrected and 0.4 corrected with −1.50/−0.50 × 160.

The doctor said PRK would probably improve vision only to the current corrected level, approximately 0.4. The hospital focused on corneal laser and did not discuss detailed evaluation of the internal IOL–capsule system. The examination was not dilated. Communication was through an interpreter, who suggested amblyopia; this was not presented to me as a diagnosis confirmed and explained by the doctors, and no functional testing was performed to establish it.

Hospital A — August 15, 2026

Postoperative Heidelberg Engineering ANTERION measurements showed 2.66 D of total corneal astigmatism at 88°, corneal HOA RMS 0.28 µm at 5 mm, pupil diameter 7.2 mm and pupil-center offset 0.31 mm at 278°. The surgeon considered the corneal map regular.

The report incorrectly classified the eye as “No surgery, Phakic, Vitreous only,” and no dedicated IOL Analysis page was obtained. I therefore still have no validated quantitative measurement of IOL tilt or decentration.

Clinical testing recorded 0.7 both uncorrected and corrected with plano/−1.00 × 170, but I was recognizing blurred letters partly by guessing. The surgeon reported no PCO, no obvious IOL tilt on routine examination and approximately 1.00 D residual astigmatism. PRK was not recommended because the expected gain was small and it could make vision worse. IOL exchange was also not recommended because of surgical risk. I am not requesting exchange without evidence, but I would like assessment by a surgeon experienced in complex IOL exchange before that option is dismissed.

During the same examination on August 15, 2026, the doctor tested my near vision using that day's correction (plano/−1.00 × 170) plus approximately +1.75 to +2.00 D ADD. Near text was then clear and comfortable.

Home pinhole experiment — non-standard

I repeated this informal test using several homemade apertures and rotated them in different directions.

• At approximately 1.5 meters, a 2–3 mm aperture could make small computer text comfortably readable; under the best conditions, subjective sharpness reached approximately 85–90% of the right eye. Larger openings brought back blur and light streaking.
• At phone-reading distance, normal text was unreadable without optical correction. A 1–2 mm aperture allowed some reading, although still with difficulty; at approximately 3 mm it became distinctly blurred again.
• Through a small aperture, the central area remained readable, nearly circular and symmetrical but slightly darker/softer. Part of the periphery appeared brighter/sharper, creating a non-standard C-shaped appearance.

This was not standardized and does not prove IOL decentration or localize the cause.

What seems less likely, but is not absolutely excluded

• Major IOL power error: preoperative calculations and current refraction are relatively close to plano.
• Ordinary refractive error alone: multiple spectacle corrections provide little improvement and do not remove the ghosting.
• Major macular structural disease: OCT and fundus examination did not identify an explanatory lesion.
• Gross corneal irregularity as the sole cause: preoperative and latest ANTERION corneal HOA values were relatively low. The doctor described the latest map as fairly regular and symmetric, mainly blue with some symmetric yellow areas and no obvious focal orange/red hot spot. Map colors depend on the display scale, so a corneal contribution is not completely excluded.
• Dry eye as the main cause: blinking and artificial tears do not change the characteristic image.
• PCO or another obvious abnormality of the capsule holding the IOL: the doctor examined this carefully on August 15, 2026, and found none. I therefore no longer consider it a leading possibility. A very subtle abnormality cannot be excluded completely because I do not have photographs for comparison.
• Severe amblyopia: during the August 15, 2026 examination, near vision became clear with plano/−1.00 × 170 plus approximately +1.75 to +2.00 D ADD. Vision can also improve substantially through a small aperture. Mild amblyopia or another functional abnormality has not been excluded; a normal OCT alone cannot diagnose or exclude amblyopia.

What remains uncertain

• Whether the IOL is tilted. This has not been measured. I do not know whether the ANTERION can perform the required analysis, and my doctor did not appear certain about this.
• The range-of-vision optical design of the RayOne Galaxy may not suit my eye. If this were confirmed, one possible option might be exchange for a different IOL—but only after every other reasonable cause has been excluded.
• The IOL power or toric correction may be inaccurate, although this remains unconfirmed because residual refractive astigmatism has measured only approximately 0.5–1.0 D, depending on the examination.
• Could vitreous scatter be contributing? I currently consider it less likely because it has not been quantified, and none of the doctors seemed to suspect it.
• Residual astigmatism or another corneal optical problem currently seems less prominent because the latest corneal map was considered fairly regular and spectacle correction—including correction of the astigmatism—improved vision very little.
• A subtle retinal or optic-nerve abnormality not visible on structural OCT.

My goal and request for advice

I believe my left eye may have better visual potential than my current day-to-day vision suggests. I am not demanding guaranteed 20/20 vision. I want a stable, readable and comfortable image, ideally without glasses or with as little dependence on them as possible.

PRK is not currently an option I am considering because the doctors expect little benefit or possible worsening. I also do not want any irreversible procedure merely as a trial. I am uncomfortable treating “amblyopia,” “vitreous opacity,” “the IOL looks fine” or “nothing more can be done” as final explanations without confirming tests.

Has anyone managed or experienced a similar case? What was the final cause, and how was it managed? Based on all of these data, which hypothesis would you consider most likely? Which specialist or examination helped confirm the cause in your experience?
